The system timer does not work correctly (windows xp / motherboard), how to cure?

Question

DOS

Hello!
Can you tell me why on a laptop (Aspire E5-521, the one with UEFI) the bootmenu of operating systems (grub4dos, xp) does not work correctly, namely:
Given time, let's say 20 seconds, so the bootmenu does not work it out in
real 20 seconds , and several times faster, for example, a menu item will be selected in 5 seconds.
UEFI is configured in legacy mode. I
loaded DOS from a flash drive, the output of the time command showed that in 10 real seconds 60 seconds pass at the computer, that is, 6 times faster than expected.
XP has such problems (I put it from a flash drive):
1. The XP installation starts, where there is a blue screen and before choosing where to install the OS, then a black screen and after it the partition selection does not always appear.
2. The stars aligned and a selection of partitions appeared, then we put it on the partition and the installer restarts the computer. A black screen appears with the Windows XP logo and a slider, so it can go further, or it can "freeze" (the slider runs).
3. Installed Windows XP, but each reboot reminds me of the 2nd item (Windows XP logo and slider)
I installed Windows 8.1, it seems to work fine.
Yesterday I installed Ubuntu, it works fine too.
Grub2 (the default one) is timing correctly...
Windows XP - 32 bits
Windows 8.1 - 64 bits
Ubuntu - 32 bits

Answer 1

Well, antiques is fine (Windows XP is almost 14 years old), but what's wrong with installing Ubuntu 64 bits?
