i try to recover an old install ..

[AkoZ]

the 1st matter comes from the fact i accept 20.10 dev upgrade .. which broke my nvidia driver install. now i've to try to keep my files.. seems ok .. but to crash and make new install on the old ones...
i used usb boot

* there is a problem significant with the EFI matter (as i activated it in bios .. (normal)
* but install crashed twice, even creating an efi partition ..
for no rescue ,no rescapp app permits to get back ubuntu 20.04
.. i 'll go to rea about efi .. and have a clean partitions mode

thanks for your great work ! keep safe !
