Grub lost after windows 8.1 update

Postby aless80 on Tue May 13, 2014 4:20 pm

Hi,
i am trying to recover the grub on my computer having a dual partition with Windows 8/Linux Mint. I hope I did not screwed windows up as well cause the last time it did not run. I had Refind allowing me to choose between Windows and LinuxMint. I tried many methods:
boot-repair under Linux Mint live usb gave me some commands to run which failed,, and eventually said that something went wrong. The last link I have is [url]paste2.org/D3NVvEtx[/url]. Rescatux (ie super-grub usb) did not word either. The "chroot" method is also not working:
Code: Select all
sudo mount /dev/sda5 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
mint / # grub-install /dev/sda
Searching for GRUB installation directory ... found: /boot/grub
The file /boot/grub/stage1 not read correctly.
mint / # grub-install --recheck  /dev/sda
Probing devices to guess BIOS drives. This may take a long time.
Searching for GRUB installation directory ... found: /boot/grub
The file /boot/grub/stage1 not read correctly.
 

The file /boot/grub/stage1 not read correctly.
My linux mint partition is on /dev/sda5: ext4 915 Gb with flag msftdata, whereas Windows is on /dev/sda2 fat32 with 925Gb and flag boot.

I hope you can help, and please be clear if you do.
Thanks in advance

Microsoft tries to prevent to use linux .. :wink:
http://www.muktware.com/2014/03/windows ... ader/24521
A Linux and Windows 8 user has reported on Reddit that one of the updates performed by Microsoft’s OS Windows 8 deleted the GRUB boot loader and set UEFI to secure boot. It was not Windows 8 to Windows 8.1 upgrade, but regular Windows 8 system update.

Grub4Dos boot-CD may helps for booting linux?

I cannot run .exe files in grub4dos, I lost my windows boot as well. Sorry in case I am misunderstanding your suggestion.
If it helps, see this:

GRUB4DOS includes...
    BOOTLACE.COM for making a legacy BIOS MBR that looks for...
    GRLDR in any partition on the system
    GRUB.EXE for starting kernels from a DOS prompt.
But it's for DOS; real-mode 512KiB DOS.
Still not work? Do you behind a proxy? Let's Ping!

GRUB4DOS will be useless on aless80's EFI-based computer.

Aless80, since you say you were using rEFInd before, my recommendation is that you simply re-install it. If necessary, you can use the rEFInd CD-R or USB flash drive to get booted initially.

You haven't provided any links to this "different thing," and my attempts to find it have been unsuccessful. This makes it rather difficult to evaluate the software to which you're referring. That said, the last I heard, GRUB4DOS was a BIOS-mode boot loader, which will be useless on a computer that's set to boot in EFI mode. Unless this version is radically different, it will be of no use whatsoever to aless80, who clearly has an EFI-mode Windows installation. (Unless aless80 decides to convert from EFI-mode to BIOS-mode booting, which will be a major hassle.)

Hi,
I was trying to use grub4dos from this link http://www.themudcrab.com/acronis_grub4dos.php and did I made a USB. I still have to grasp what they want me to do with the Acronis ISO etc, I think they want me to download that from another site..

In the mean time I am using rEFInd, which I better understand. I made a rEFInd CD and I see the following icons:
Code: Select all
Boot Microsoft EFI boot from SYSTEM
Boot EFI\refind\refind_x64.efi from SYSTEM
Boot EFI\refind\grubx64.efi from SYSTEM   
Boot from vmlinux.. #some leftovers from Ubuntu


The first allows me to boot to Windows! I am very happy because I was afraid I had lost it. I am going to make a recovery disk with it.
The second says:
Code: Select all
Starting refind_x64.efi
Using load options ''
Error: Volume Corrupt while loading refind_x64.efi

The third has the icon of Linux Mint and used to boot to that OS, but now it sends me to the Grub. I guess those .efi files are a mess.

I am going to see if I manage to install rEFInd from Windows or from live Linux Mint. Another viable option is to reinstall linux Mint on its partition. If you have suggestions on the next steps please let me know and thanks for your help so far

I am trying to install refind from Windows following the instructions in the site of rEFInd:

Command Prompt as Administrator:
Code: Select all
mountvol S: /S
xcopy /E refind S:\EFI\refind\
S:
cd EFI\refind
del refind_ia32.efi
rd /s drivers_ia32
rename refind.conf-sample refind.conf
bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi

I get this error:

The parameter is incorrect

but when I reboot rEFInd is there and can boot in Windows. Now I would like to recover the Linux Mint partition, if possible.

That's good news. Are you able to boot to Mint (either directly or via GRUB)?

The second says:
Code: Select all
Starting refind_x64.efi
Using load options ''
Error: Volume Corrupt while loading refind_x64.efi


This suggests filesystem damage. Before doing anything else, I recommend backing it up. (A file-level backup, via tar, cp, or whatever, should be adequate.) Once that's done, unmount the ESP and run dosfsck on it, as in:

Code: Select all
sudo umount /dev/sda2
sudo dosfsck -a /dev/sda2


This type of problem can occur for several reasons. One of them is a failure to deactivate Fast Startup in Windows, as described here, among other places. (Note that the Windows Fast Startup feature is different from similarly-named features in the firmware. The Windows feature must be disabled in order to safely dual-boot. The firmware feature is less of a problem, although many people recommend disabling it, either because of confusion or because the firmware feature can cause problems on some computers.) If you haven't already done so, you should disable that feature.

The third has the icon of Linux Mint and used to boot to that OS, but now it sends me to the Grub. I guess those .efi files are a mess.


This is the EFI\refind\grubx64.efi entry? You might find rEFInd under that name if you installed rEFInd with Secure Boot active (since the Shim boot loader chainloads to something of that name). Perhaps you ran Boot Repair and it swapped it out; or maybe something else happened to accidentally put GRUB in the rEFInd directory.

I am trying to install refind from Windows following the instructions in the site of rEFInd:

Command Prompt as Administrator:

Code: Select all
mountvol S: /S
xcopy /E refind S:\EFI\refind\
S:
cd EFI\refind
del refind_ia32.efi
rd /s drivers_ia32
rename refind.conf-sample refind.conf
bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi


I get this error:
Code: Select all
bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi
The parameter is incorrect


but when I reboot rEFInd is there and can boot in Windows.


It's odd that you got an error, but at least it worked....

Now I would like to recover the Linux Mint partition, if possible.


You do have Linux kernels on your /dev/sda5. If you've installed an EFI filesystem driver for whatever filesystem you used there (ext4fs by default), you should see them in the rEFInd menu. They might show up with Ubuntu or Linux penguin icons, though. (The tricks rEFInd uses to identify the Linux distribution aren't 100% reliable, and in particular Mint usually shows up as Ubuntu.)

Hi,
thank you for your post. No, I am not able to log in to Mint. When I go through the icon in rEFInd it goes to the grub. Fast boot and secure boot: the ones I can access from UEFI are off. I will double check in Windows following the instructions from your link.

About dosfsck, I did it for all partitions in Mint live:
Code: Select all

I run the recommended repair of boot-repair in linux live and got the errors below. When I reboot and press Esc/F9 I see a new "linuxmint" booting option which does not work, and rEFInd does not work anymore. LUckily I can boot to windows with rEFInd cd. I am going to repeat the steps in the command prompt as done above.

Re: Grub lost after windows 8.1 update

Postby srs5694 on Sat May 17, 2014 12:50 pm

First, when running dosfsck in Linux, you should include the "-a" option. (You omitted it from your command.)

Second, if you want to continue using rEFInd as your boot manager, installing GRUB is probably not what you should be doing. Note also that Boot Repair installs GRUB, and may do so quite aggressively, replacing the Windows boot loader with another copy of GRUB.

I recommend you concentrate on figuring out why rEFInd is not presenting your Mint kernels. Can you find those kernels from the emergency disc that you're presumably using? If so, where are they? On what type of filesystem (ext4fs, Btrfs, etc.)? Do you have rEFInd drivers for that filesystem? Can you launch an EFI shell from rEFInd, and if so, can you find your kernels using it? Have you uncommented the "scan_all_linux" option in refind.conf? Some of these possible problems will affect GRUB, too, and automated tools won't be able to fix them, so figuring out what's going on yourself may be necessary no matter what type of solution you adopt.

Hi,
Now I understand why boot-repair messes up my dual boot.
I decided to re-install Linux Mint over the old one, so now I have a clean dual boot. Thanks to everybody.
