Why can't GRUB see the external HDD?

Question

linux

I have an external hard drive with Kali Linux installed. When you turn on the laptop, an error pops up (see screenshot). If I start GRUB manually through the Boot Menu, then it finds external wines, otherwise it gives out such nonsense.

Answer 1

Is the BIOS configured to boot from this hard drive? If not, then perhaps the system is running the disk installed in bios by default.

Answer 2

I had a similar question on LOR here
Try reinstalling Grub via Live CD.
