grub reinstallation broke win11 and arch

Installing windows 11 made arch inaccessible, trying to boot into it would send me to (iirc) grub rescue, so I booted from a live USB and reinstalled grub using grub-install and mkconfig and that broke windows as well, I don't know what kind of logs I should post and I currently  don't have a functional os on my computer

Re: grub reinstallation broke win11 and arch

from your nvid topic: LENOVO 20LB000BUK = Lenovo ThinkPad P52
would be nice to open your post in laptop area and note your system model instead of others have to figure it out

Re: grub reinstallation broke win11 and arch

Mod note: Due to the nature of the problem (killing Arch with the installation of another operating system), I'm keeping this thread in the Newbie Corner for now.

@OP: Please provide some information on the firmware type (BIOS or EFI) and the method (MBR or UEFI) with which you boot your computer as well as the partition layout of your disks:

# lsblk -o +fstype,parttypename,pttype
