Thanks for your interest.

Well, it was UberStudent 4.0. I tried to install it several times from USB and disc, and it was not possible to finish because every time it gave some error (that was strange because with 3.0 all went OK). I worry that the same thing can happen now. BTW, I was really happy when the system updated itself to Epicurus and Heraclitus without to have to reinstall all again!!

On that occasion I installed the OS with the machine in BIOS legacy mode, not in UEFI mode, and the installation program asked me for a special partition for Grub. I don't remember the details. As a result, it was necessary to follow different "boot paths" if one wanted to use Uber Student or Windows, until I ran Boot-Repair-Disc. It reinstalled Grub in UEFI mode, so now one can boot either into UberStudent or Windows from the same menu. I like that and don't want to change it.

If I couldn't install UberStudent this time I'd have to work full with Windows or to use other Linux in the meanwhile, but I like UberStudent :).

I used Boot-Repair-Disk because when I turned on my laptop, a "grub rescue" prompt appeared on the screen. This fixed the problem, but unwanted changes occurred, maybe due to changes in the installed packages the program did. I had have to reset my laptop three times or so because it got really slow and finally it froze.

The very fact that a GRUB rescue prompt randomly appeared and required boot repair suggests the possibility of a hardware issue, specifically the possibility of a failing hard-drive. The freezing issue trumps all of the other issues you have listed, and further suggests the possibility of a hardware issue. If your hard-drive is modern enough to have S.M.A.R.T. technology you could analyze your hard-drive with smartctl.

Well, it was not really randomly, it happened just after I modified, from Windows, two data partitions (which I think is strange because they aren't boot partitions). But yes, GParted suddenly closes if it tries to work with one of these partitions (taht's why I went to Windows). Perhaps there are bad sectors, although I didn't think it could be very serious.
Thanks for the advice, I'll use smartctl to check the HDD.

Hi!
Here is what I think is the relevant information about the state of the HDD:

OK... How bad is that? :?
Should I post more info?

That Reallocated_Event_Count of 8000+ indicates that bad sectors were encountered, but it has not crossed into its predefined threshold of FAILING_NOW yet. I am not sure what to think of the fact that bad sectors have been encountered yet the reallocated sector count (Reallocated_Sector_Ct) is still zero; is your hard-drive failing to reallocate sectors when bad sectors are encountered, or does your hard-drive have only a partial implementation of S.M.A.R.T. reporting such that reallocated sectors are not being tracked? That Seek_Error_Rate of 21.6 billion+ also seems rather high. Has this hard-drive shown any other instances of data loss or corruption?

Uhmmm ... No, I don't think so ... Only what I mentioned before about GParted closing when working with those partitions. But after I deleted them and made new ones (don't remember if from Windows) GParted has not "complained" again.
Then, do you think is my disk at risk? How long is the life of a hard drive?
