Windows 10 upgrade lead into grub rescue

I was dual-booting Windows 7 and Linux Ubuntu on my desktop, and today is the day they gave out free Windows 10 upgrades. How exciting! I got the update, and it was installing, and I left to go take a 30 minute nap. However, when I came back to my computer, it led me to the grub rescue prompt.

error: no such partition. Entering rescue mode... grub rescue>

I get the following when I type ls:

grub rescue> ls (hd0) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)

After a quick look through of people who encountered the grub rescue prompt, I typed set and got the following

grub rescue> set cmdpath=(hd0) prefix=(hd0,msdos6)/boot/grub root=hd0,msdos6

I was still kind of lost after finding that certain commands like normal didn’t work, and then I found a video tutorial where you boot from a Linux image cd and run some commands on the terminal....

My computer came with Windows 8 pre-installed so I shrunk the Windows partition to make room for Ubuntu. That is how it worked for the last year. After the second reboot in Windows 10 upgrade the computer did not boot any more. GRUB only displayed a grub rescue command prompt. I found out later that the problem occurred because Windows somehow changed the partition scheme. The boot partition (containing normal GRUB data) was no longer where GRUB expected it. I don't know how and why this happened.

The first thing that you can do in the rescue mode is to see the partitions with the ls command. Mine were:

(hd0,gpt1), (hd0,gpt2), etc.

Try to find out which partition is your boot partition. There is no Tab completion, you have to type it out completely. I tried the following commands until I found the right partition:

ls (hd0,gpt1)/ ls (hd0,gpt1)/boot ls (hd0,gpt2)/

etc.

Then type set in the same prompt. It will display where GRUB looks for its files. In my...

Hello Jackson,

Thank you for posting your query in Microsoft Community.

Sorry for the inconvenience caused with Windows 10.

Are you able to boot to Windows 10 with flash drive plugged in?

If you are able to boot to Windows 10 with flash drive plugged in, you may follow the below steps.

a) Press Windows Key + R Key, Run window will appear.

b) Type msconfig and hit enter. System configuration box will open.

c) Click on Boot tab and check if you see Windows 10 Current OS in the box. If you see Linux OS here make sure you have selected Windows 10 Current OS and then click Set as default and OK.

I suggest you to run Startup repair from Advance boot option.

It may ask you to insert the Installation DVD/USB while doing startup repair.

If you don’t have an installation media, you have to create an installation media for that.

You may download an ISO from the below...

I have an older laptop that I dual-boot between Linux Mint and Windows 10. I recently tried to update Windows 10 to the newest version. After letting the update run and the PC restarting I was greeted with the wonderful GRUB Rescue screen. I tried going through each partition listed looking for /grub2 or even a filesystem that was recognized but all the entries give the "unknown filesystem" error.

This has happened before and I'm pretty sure I re-installed Mint which re-installed GRUB, which is what I'll try next. What I really want to know is how I can stop this from happening. What is Windows 10 doing to screw things up so royally and what can I do to prevent this from happening again in the near future?

I've tried to find some answers online but I can't find anything, either on how I can fix GRUB without reinstalling or why Windows 10 does what it does. Any help on this would be greatly...

It’s holiday season and so I got a hold of playing some games longly missed on Windows. Booting Windows 10 certainly unveiled several pending updates (Antivirus, Geforce, Windows updates). Since Windows 10 does not explicitly tell about big updates anymore I just did let it reboot several times, waiting for manual grub selection then.

Though this time the update essentially broke GRUB. “error: unknown filesystem. Entering rescue mode…” is certainly not what I expect from a Windows 10 update. After googling a bit I found this thread including an explanation as well as a solution for the problem: The Windows 10 update adds yet another hidden partition, but essentially rewrites the partition table which then breaks GRUB finding the correct /boot partition containing grub2/. Congrats Microsoft!

So, Windows 10 “Upgrade to Windows 10 Home, version 1511, 10586” breaks grub2 because boot block grub2 still thinks it should boot grub2 from (hd0,msdos2) when it now needs to boot...

Brief: Cannot access Linux in dual boot because system boots straight to Windows without showing the grub menu? Here is a possible fix for you.

So, finally, I upgraded Windows 8.1 to Windows 10 last night. Since, I dual boot Windows 8.1 with Ubuntu, I was expecting to see the Grub menu at the boot so that I could choose the operating system of my choice. But the upgrade to Windows 10 from Windows 8.1 messed up the settings and it never showed Grub menu. It just kept booting into Windows 10 at each start up.

Frustrating, isn’t it? It seemed like as if there is no way to access Ubuntu at all. No! the Ubuntu install on the other partition was fine. It was just the UEFI settings that were different in the boot manager. I verified everything by accessing UEFI firmware settings in Windows 10.

If you too are unable to boot into Grub and rebooting Windows 10 repeatedly, I am going to present you the simple solution that worked for me.

I had* a dual boot setup with opensuse Linux along with Windows 10, the Windows 7 to 10 upgrade didn't do anything to my boot manager. But when updating the fall updates on windows 10 today, one of the reboots took me to the grub rescue console. I didn't have a grub rescue handy couldn't make one. None of the Grub commands I looked up worked, only "ls" worked, nothing else.

But here is how I got back into windows:

I booted into BIOS and switch under boot options from the "GRUB boot manager" to "Windows Boot Manager" and it booted into windows, finished the update and here I am to warn you.

Next step is to create a Grub boot rescue disk and try to fix it, and if it fails, oh well, looks like this laptop will be a windows only thing.

I hope this helped you if you needed...

Error No Such Partition Grub Rescue Windows 10


Nowadays there are always many disk or partition problems during the process of using a laptop or desktop. Some problems including black screen, blue screen, system breakdown, system restart, or system file corruption often occur on your computer. When an issue appears, usually it is followed by a message which informs you the specific error. Among them, no such partition error in Windows is very common, which is very common in the dual system. It always appears when you boot your computer, then an error message "GRUB loading. Welcome to GRUB! Error: no such partition. Entering rescue mode… grub rescue>" or "error: no such partition. grub rescue>" is following, just like the following pictures show.

An example is here:

So today is the day that Microsoft let Windows 10 out the door.

Great, but compared to how we do upgrades in Linux, the Windows 10 upgrade is nothing to rave about. But that’s another discussion that I don’t have time for now, and I don’t think I’ll ever.

This short post is for those running a system on which Windows 7 or 8 (or 8.1) is installed in dual-boot fashion with one or more Linux distributions. If you have such a system and are wondering whether the integrity of the Linux side will survive an upgrade to Windows 10, well, it depends.

Let me explain…

If the setup is on a computer with UEFI firmware, with the boot files of all systems on the EFI Boot Partition, then I don’t see anything that will mess GRUB up during or after upgrading to Windows 10. That’s because the EFI Boot Partition is like a public park, where the space occupied by each operating system’s boot files is respected. So the Windows 10 upgrade script will only update the files and...

The first thing I would recommend is to make a Disk Image of your entire hard drive before going forward. Then mount the disk image and confirm that it is viable by inspecting the contents in File Explorer, confirming you can open file (docs, music, images, etc.), to confirm that you have a strong fall back option.

Then you will likely have to .....

@amit946

Hello;

Allow me to welcome you to the HP forums!

I'm going to guess that, at one time, you had a Linux distro installed on this same PC -- as that is how GRUB got installed on it.

When Linux is installed in this situation, it installs some boot code in the Master Boot Record (MBR) of the drive, and installs the remaining GRUB code in the boot partition of the Linux OS. That causes the PC to boot into GRUB automatically.

When you deleted the Linux partition(s), you left the MBR intact -- and it is STILL looking for the GRUB code in the Linux boot partition -- but that is gone, now.

You have to rebuild the MBR so it points to the proper Windows filesystem partition to boot Windows.

You will need access to a working PC for this step in order to create the media needed to repair your PC boot loader.

Once you have that, please download and create Win10 install media from this link:...

I have a multi-boot machine with a Ubuntu 14 partition, an ubuntu 16 partition and a Windows partition (probably Windows 10). I hadn’t used Windows in over a year and after rebooting, it forced me into Windows updates. After that, my machine won’t reboot. I get to the GRUB rescue prompt. The only error message is

error: no such partition

I could not run any useful commands from the GRUB rescue prompt, so I removed the hard disk and mounted it on a separate Ubuntu PC. I ran parted on the disk and this is what it looks like:

Disk /dev/sdb: 2000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1049kB 525MB 524MB primary ntfs boot 2 525MB 1015GB 1014GB primary ntfs 3 1015GB 1015GB 891MB primary ntfs diag 4 1015GB 2000GB 985GB extended 5 1983GB 2000GB 17.1GB logical linux-swap(v1)

Previously I had installed the Ubuntu 10.04 and Windows 7.

Now I logged on to Windows, opened the partition editor and deleted the volume containing the Ubuntu - I thought it will delete the Ubuntu and it might help me install another OS - and I restarted the system.

GRUB rescue prompt is there.

I want to log on to Windows. How can I do that?

In GRUB rescue, I tried the following:

ls (hd0) (hd0,3) (hd0,2) (hd0,1) (hd1) (hda1,1)

Tried all combinations of ls (hdax)/, which threw out:

error: Unknown Filesystem.

I tried this:

rootnoverify (hd0,0) chainloader +1 makeactive boot

It threw out:

Unknown command.

EDIT:

I installed Ubuntu from the USB. Now when I restarted the system, I got the GRUB, showing old Windows and the newly installed Ubuntu. I happily logged onto Windows. Then I used standard procedure to remove Ubuntu, so as not to have grub...

I took Microsoft up on the offer to upgrade my Windows 7 install to Windows 10 for free and am now unable to boot into any of my operating systems. I have a 2TB data drive and a 256GB SSD that my OSes were installed on. It's been so long I don't remember how the boot was configured though I do remember there were some complications with it when I initially set it up. If I am interpreting the boot info log correctly that complication may be that my Windows MBR is actually on my 2TB data drive and not the 256GB SSD OS drive. I have tried the boot-repair program from a Live Ubuntu USB and did not see any change in boot behavior. Before I go messing with anything else I wanted to see if anybody had any recommendations for which step I take next.

grub rescue shows:

Code:

(hd0)
(hd0,msdos5)
(hd0,msdos3)
(hd0,msdos2)
(hd0,msdos1)
(hd1)

Which all produce the error 'unknown filesystem.' when I try the ls command on them.

Do you have a dual boot setup of Ubuntu & Windows? Did you update your Windows 10, then suddenly you're encountering grub rescue where the error is no partition found? Just like that, BOOM! Your computer is not working.

Scary ha? Don't worry there still hope - thanks to TestDisk & Christophe Grenier who created it.

Here are the steps you can do:

Checking Bootable Partitions

Restart your computer In the Grub rescue, type ls. This will list all of the partitions in your computer. Check each one, Ex: ls (hd0,msdo6) If you found a partition with extension File Ext4, its the bootable partition. If not, then skip to Restoring bootable partition. Set the bootable partition. Ex: (hd0,msdos6) is the bootable partition. - set prefix=(hd0,msdos6)/boot/grub - set root=(hd0,msdos6) - set boot=(hd0,msdos6) - insmod normal - normal
