So, I blindly installed F32 from USB expecting a dual boot option to automatically appear at power-up. I have Windows 10 with UEFI (I think). The only partitioning I did, all during install from USB, was reduce the size of the W10 data partition and create new a fedora partition, sda7. Now I can’t seem to boot W10. When I power on, the computer goes straight to the fedora logins screen. I would think this is an easy fix but the topics I looked at don’t seem to apply to me given
- My original boot partition created by W10, sda1, is not mounted
- I have no option in BIOS to select a boot file.
- After mounting sda1 to /temp/hoho I suspect the boot file is /temp/hoho/EFI/Boot/bootx64.efi
- I did
%sudo dnf reinstall grub2-efi grub2-efi-modules shim
%sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
- The file /boot/efi/EFI/fedora/grub.cfg exists for me.
- % efibootmgr
EFI variables are not supported on this system.
I decided to post this topic when another thread said to create a new sda1 partition. I really don’t want to irreversibly damage my W10 - if I haven’t already. Any help would be greatly appreciated. I don’t mind nuking my F32 install as long as I can get my W10 back. Thanks in advance.
