change /etc/grub.d/40_custom window entry to this

Code:

menuentry 'windows' --class=windows{
search --no-floppy --fs-uuid --set=root 06ED-BE24
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

and rerun grub-mkconfig

MUSTDOS · 05-28-2021, 04:05 AM

It gave me /EFI/Microsoft/Boot/bootmgfw.efi was missing

note that when I performed this as chroot

ls /boot/efi/EFI

Only the parabola folder was present, no windows folder

You are mounting the efi partition to either /mnt/boot/efi out of chroot or /boot/efi within chroot? With /etc/default/grub file missing you may need to re-install the grub package, then rerun grub-install and grub-mkconfig

MUSTDOS · 05-28-2021, 08:14 AM

Uninstalled by pacman as chroot and reinstalled everything as root by parabolaiso ~ # pacstrap /mnt grub efibootmgr dosfstools os-prober mtools

and got these errors

Good news!

Turns out I had to reinstall the kernel since I was wiping out the boot/efi directory everytime to reinstall grub and efi stuff; there are some files there related to the kernel!

I should try the same with windows when I get my hands on an installation disk and try to copy the missing file!

I still have an issue with the windows partition,

I got the bootmgr file running but now I have a BCD issue

http://rajandmk.blogspot.com/2012/09...le-to-fix.html

My windows 7 cd installer claimed it was incompatible with my windows hdd for some reason so I'm using the command prompt

I tried the second command

bootrec.exe /fixmbr
X:\boot\bootsect.exe /nt60 all /force

It oddly didn't work unless I used bootsect.exe /nt60 all /force

However, when I tried the rest

del C:\boot\bcd

bcdedit /createstore c:\boot\bcd.tmp
.................

It said it couldn't delete boot because it didn't exist
Nor I can use bcdedit since it also doesn't exist

So I tried mkdir c:\boot
And it told me it can't create the boot directory since it already exists as a file or folder

I used DIR un c: and found no boot.

How should I continue?

Windows 7 doesn't do uefi mode, you will need a windows10 installer to reinstall windows bootloader in uefi mode.

Thanks all for your help, forgot to lock this thread

Now, I just have to deal with my slow internet.
