Running a live system from a USB flash drive is always faster then from HDD, it's normal.

you are right but open firefox or libre office take 4-5 minutes. that is not normal.

[nevertheless]

Have you tried a different hard drive? (Is it possible yours is failing? Or the cable is bad?). Do other distros do the same thing? (Bodhi Linux, Antix are lightweight ones that come to mind and could be tested).

I've seen weird problems due to not verifying the .iso checksum. Some bit corruption lets it boot the livecd desktop, but the install will be bizarrely afflicted (or vice versa; it's random weirdness). Or, have you run memtest86? I've had bad memory that Windows never touched in a way to be a problem, but a linux distro did. Memory was the absolute _last_ thing I thought it could be, and memtest86 found it in 30 minutes. (So, I'd rule out the checksum and memory, as foolish as it may sound.).
