Guest Windows XP won't start

[j4neski]

Hi,

I'm a kind of newbie with VirtualBox and now I've faced a weird problem. I have a Ubuntu 10.10 as a host operating system and Windows XP Pro as a guest system. Everything works just fine, but some softwares needs to SP2 be installed to XP. So, after SP2 installation, system wants to reboot, that's fine. But now VirtualBox cannot boot XP up and it try to reboot it forever. XP boot go further until XP start-up screen appears (XP logo and a running bar) but after a few seconds it disappoears and VirtualBox reboot again. Any ideas?

Many ideas possible. Dont post "does not work". Post details like exact guest configuration and log file.
