如题，继昨天的修复引导，今天我在PE用Disk Genuis又重新搞了一个ESP分区，然后我就想用boot-repair修复一下引导，结果修复失败了，大家知道这是什么问题吗？

Default settings: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub2 of
sdb2 into the MBR of sdb.
Grub-efi would not be selected by default because legacy Windows detected.
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix

Blockers in case of suggested repair: __________________________________________

GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again.
Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.

Confirmation request before suggested repair: __________________________________

LegacyWindows detected. The boot of your PC is in EFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode.
Are you sure you want to continue anyway?

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your BIOS boot on sdb (ATA ZHITAI SC001 Act) disk!
Please set your BIOS in Legacy mode in order to start your Deepin 20.8 (20.8), then type command [sudo update-grub] in order to add the Windows entry to your GRUB menu.
