[SOLVED] Can't boot Windows 8 using grub2. invalid EFI file path

English is not my native language. Please excuse typing errors.

I have just successfully installed Arch linux with grub2 as its boot manager. I
followed the arch beginner guide. I've used grub before and I'm familiar with
it, so chose to use grub instead for efistub. I installed os-prober and
ran grub-mkconfig to create the grub.cfg file. The problem now is that I recieve
an error when I try to boot windows 8. I have two drives (/dev/sda and /dev/sdb)
and I believe both are EFI-systems.

However, it's not very important for me to use grub, so if booting into windows
8 is easier using efistub, I will try that.

The computer is ASUS ux32vd with a hybrid disk with 25GB on the SSD and 500GB on
the hard drive. I believe the SSD part is used by Windows.

This is the first error I recieved when I tried to boot windows.

error: can't find command `drivemap'.
error: invalid EFI file path.

Press any key to continue...

Then I tried to follow this post
https://bbs.archlinux.org/viewtopic.php?id=150183 and made a new boot
entry "Windows 82". And I got a new error:

error: unspecified search type.
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found

Press any key to continue...

Here are some command line outputs.

EDIT:

I gave up trying to make grub work, so I uninstalled grub and deleted all the grub files I could find. 

# pacrem grub-efi-x86_64
# rm -fr /boot/grub

That last one I came to regret later on. So I installed rEFInd using the archlinux beginners guide. When I then tried to boot into windows It told me that /boot/grub/x86_64-efi/normal.mod was not found. I then reinstalled grub-efi-x86_64 and copied /usr/lib/grub/x86_64 to /boot/grub. Now everything works fine.

Re: [SOLVED] Can't boot Windows 8 using grub2. invalid EFI file path

sighol wrote:

However, it's not very important for me to use grub, so if booting into windows
8 is easier using efistub, I will try that.

The EFI stub loader is a Linux-only boot loader; however, it is possible to use the EFI stub loader in conjunction with a separate boot manager, such as rEFInd or gummiboot. In such a configuration, you'd use the boot manager to select the OS to boot (Windows or Linux, and possibly the specific Linux kernel), and the boot loader (the Windows loader or the EFI stub loader built into a specific kernel) will then take over booting the OS. In Arch, this is often easier to configure than is GRUB, since GRUB is very complex and its automated tools to help with setting things up often get it wrong.

This is the first error I recieved when I tried to boot windows.

error: can't find command `drivemap'.
error: invalid EFI file path.

Press any key to continue...

The "drivemap" command in GRUB is generally used when booting a BIOS-mode boot loader, and in fact your "Windows Recovery Environment (loader) (on /dev/sda2)" and "Windows 8 (loader) (on /dev/sda4)" GRUB entries are both built as for BIOS-mode Windows installations -- but the fact that your disks both use GPT means that Windows won't boot in BIOS mode on your computer. (This is one of the many things that the GRUB setup scripts can get wrong.)

Then I tried to follow this post
https://bbs.archlinux.org/viewtopic.php?id=150183 and made a new boot
entry "Windows 82". And I got a new error:

error: unspecified search type.
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found

Press any key to continue...

Both your "Windows 8" and "Windows 82" entries refer to an EFI boot loader file called EFI/Microsoft/Boot/bootmgfw.efi on your EFI System Partition (ESP). This should be correct, but your Boot Info Script output doesn't show any evidence of such a file. Sometimes Boot Info Script misses such things, so you may want to check it just to be sure. Your ESP is /dev/sda1, and it looks like it's being mounted at /boot/efi by default, so check for the /boot/efi/EFI/Microsoft directory tree, and for /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi in particular. If that file isn't present, then something is wrong -- perhaps you mistakenly erased the ESP when you installed Linux, thus wiping out the Windows boot loader; or perhaps the file was accidentally deleted somewhere along the way. (Note that on FAT, which the ESP uses, case is irrelevant, and in fact case varies between the filenames reported by Boot Info Script and what's recorded in your configuration files.)

You do have another boot loader file that may be a duplicate of the Windows boot loader: EFI/BOOT/bkpbootx64.efi. This filename is generally created by Ubuntu's "Boot Repair" tool, which IMHO can do as much harm as good, especially on a system that's not booting Ubuntu. If you ran this tool, though, it's conceivable that bkpbootx64.efi is a copy of the Windows boot loader, so copying it to EFI/Microsoft/Boot/bootmgfw.efi might get things working. OTOH, the Windows boot loader relies on other files to do its job, so if they're not present, copying the Windows boot loader to its original location won't be sufficient.

If you can't get things working based on the preceding suggestions, I recommend you run a Windows repair tool. These are accessible from a Windows recovery disc. Such disc images are readily available on the Internet, but I don't happen to have any links handy. Try Microsoft's own site; images obtained from random third-party sites might contain malware. Once you've done this, chances are the computer will boot directly into Windows. You'll then need to either restore GRUB as the default boot loader or install another boot loader or boot manager.  You can use the Windows "bcdedit" command to do the former, as in:

bcdedit /set {bootmgr} path \EFI\arch-grub\grubx64.efi

You'll need to type this from an Administrator Command Prompt window.

Re: [SOLVED] Can't boot Windows 8 using grub2. invalid EFI file path

Thank you so much for the answer!

Actually I'm quite sure that the EFI/Microsoft/Boot/bootmgfw.efi file exists as I can run commands like these.

~  ᐅ sudo /usr/bin/diff /boot/efi/EFI/Boot/bootx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

/boot/efi/EFI/Microsoft/Boot  ᐅ la bootmgfw.efi 
-rwxr-xr-x 1 root root 119K May  7 16:34 bootmgfw.efi

It looks like the file is in good shape. As you said, it has an equal in the EFI/Boot directory.

But it didn't show in the bootinfoscript results, and it states that the file path is wrong when I boot, so something somewhere is obviously wrong.

I thought that it may be something wrong with permissions, but they have the same permissions as any of the other boot files that got discovered by bootinitscript. That includes all the folders above /EFI/Microsoft/Boot/

I had ubuntu installed before arch. Booting into windows did not work in that system either, but worked after I ran boot-repair. Is it possible to run boot-repair on arch? Should I try rEFInd instead, as suggested in the Arch Linux Beginner guide?

It's possible you're running into filesystem corruption, or perhaps your EFI is one of those that's flaky with a FAT32 filesystem smaller than 512MiB. In either case, you might try:

  1. Backing up the ESP (to a tarball or using "cp -a" to somewhere convenient)

  2. Unmounting the ESP

  3. Creating a fresh filesystem (possibly FAT16) on the ESP

  4. Re-mounting the ESP

  5. Restoring the files

The ESP is small enough that this should take just a minute or so if you know what you're doing.

I thought that it may be something wrong with permissions, but they have the same permissions as any of the other boot files that got discovered by bootinitscript.

FAT (which the ESP necessarily uses) doesn't support Unix/Linux-style permissions.

I had ubuntu installed before arch. Booting into windows did not work in that system either, but worked after I ran boot-repair. Is it possible to run boot-repair on arch? Should I try rEFInd instead, as suggested in the Arch Linux Beginner guide?

I wouldn't recommend running Ubuntu's Boot Repair tool on a non-Ubuntu system (except possibly Mint). Then, too, I'm not a big fan of Boot Repair, period. It's about as subtle and elegant as using a wrecking crane to kill a fly, and it tends to produce a lot of unintended side effects.

Re: [SOLVED] Can't boot Windows 8 using grub2. invalid EFI file path

I tried reformating the ESP, but I recieved the same errors as before. I only formated with FAT32 though.

Is it safe to just uninstall grub-efi and then follow the beginners guide to install rEFind?

Edit:

I've got it working with rEFInd now. See the EDIT-text in the first post.
