mac Mac Won’t Boot

Linux-Admirer · July 21, 2022

I dual booted my mac and tried to delete the alt boot but it failed. After booting my mac again will always boot to gnu grub. I’m not sure how to use gnu grub, so I tried using exit and halt but it just didn’t work. My boot manager refind doesn’t see my mac hard drive anymore and the recovery assistant drive manager doesn’t access the space gained from deleted the other boot. Please help me. I tried the internet recovery but the only option that can do anything is reseting my computer but I don’t want to do that.

What does `diskutil list` show on the terminal of macOS recovery mode? I wonder if you just need to fsck your old filesystem, mark it bootable, or reset your nvram or something.

Can you access recovery? See https://support.apple.com/en-gb/guide/mac-help/mchl46d531d6/mac .

If you can access recovery the disk utility there might help.
