Hi all,

I've got a problem, after upgrading Beta3 to RC, my boot menu no longer able to boot into Deepin or Windows.

Fyi, my system is Dua boot Deepin with windows in MBR disk, but after a restart from deepin, my system both windows and deepin has lost in the jungle.

Both error from windows or deepin, states out of range pointer

Any suggestion for recovery the grub? or step by step tutorial?

Thanks in advance

You can fix Grub using a LiveCD. Below might be a solution:

Download an ISO of Ubuntu/Deepin V23 RC/Debian and burn it to a flash drive using tools like Etcher. Enter the live system, then find out the label of the system drive of Deepin(formatted in /dev/sdaX or /dev/nvme0pXnY). Execute these commands:

sudo mount /dev/sdaX /mnt
sudo grub-install --root-directory=/mnt /dev/sda
