grub rescue error: failure reading sector 0x2a00802 from hd0
Hi community!
When I try to enter my linux, a grub rescue prompt appears and show me that error grub rescue error: failure reading sector 0x2a00802 from hd0
I try the following:
Code:
ls
>>>(hd0) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)
ls (hd0,gpt4)
>>>Filesystem is ext2
ls (hd0,gpt3)
>>>(hd0,gpt3): Filesystem is unknown
>>>error: failure reading sector 0x2a00802 from hd0
set
>>>cmdpath=(hd0,gpt1)/EFI/BOOT
>>>prefix=(hd0,gpt3)/boot/grub
>>>root=hd0,gpt3
insmod normal
>>>error: failure reading sector 0x2a00802 from hd0
normal
>>>Unknow command normal
It would seem to mean Grub is installed to a location on the first disk, which contains a bad sector that prevents it from doing its job.
I have two SSD in my machine: one for Windows and the other one for ArchLinux.
When I boot an arch live and run fdisk, it only shows the Windows device
Code:
fdisk -l : ___________________________________________________________

I got wrong and put it on hardware forum, when I wanted to post it here.
I have read that there is no way to delete a thread, so I will mark both as solved when I have the solution.
Check connections, your other thread fdisk from boot-repair showed the ssd but p3 had no uuid/partuuid as if there was something wrong with the filesystem on p3
