Grub Rescue: No such partition error ! Cannot boot from USB
It seems that I have to deal with a classical grubrescue issue but despite many researches I can't fix it or find answers to some questions either.
What I did ?
I bought an Asus laptop 6 years ago with windows 7 pre-installed. I immediately installed Ubuntu and this dual boot configuration was working fine until I decided to restaure Windows with the recovery partition. I choosed to re installed in the entire hdd which was not the best idea.
Therefore, I get the famous grubrescue mode.
Error: no such partition.
grub rescue> ls
(hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)
grub rescue> set
prefix=(hd0,msdos5)/boot/grub
root=hd0,msdos5
I understood the old Ubuntu partition is deleted and so grub cannot find files system on it (The 3 partitions listed are probably System, Data and Recovery partition for Win7).
I am now trying to boot on a USB drive (where I installed a clean Ubuntu or one boot-repair liveUSB) but I have to face others issues:
I could access to the bios but everything is hidden and protected by a Administrator Password (Installed during recovery set up I think).
I also tried to use rescue mode commands, but my laptop cannot read the USB partition:
grub rescue> ls
(hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos1)
grub rescue> ls (hd1,msdos1)/
error: unknown filesystem.
I get the same error when I set prefix and root to the usb partition and try to load module with insmod command.
I don't uderstand what I did wrong because I can boot and use Ubuntu from the USB drive on another laptop (Macbook Pro)..
If anyone get the same troubles and known a solution.
Thank's in advance !
