tomlukeywood you're right,it was because of lvm partitioning.I've installed
Trisquel 7 in text mode successfully.
Now i have another issue:
The X60 is costantly beeping but at lower volume than the louder beep of a
bios error code.
I'm almost sure that is not a:
Ram issue(because i've tried few sodimms)
Hard Disk (because i've run a live system with a physically removed drive)
Os (i've tried Trisquel 6 and Trisquel 7 noticing the same beepy noise)
If i scroll the page on the browser the noise get triggered and then
continues to beep.
If i open quickly lots of tabs on the browser the noise disappear until i
stop to click constantly.
Somethingwrong with the motherboard?
Might be the fan not working properly?
Is there something that i can check or try to set on the Libreboot BIOS?
