My Dad's VAIO laptop (model: vgn-fs315z), windows xp (sp3 if I remember correctly) has recently been unable to boot up. We switch it on, and it shows the screen where we can choose to start windows normally, or with the last known good configuration, or in safe mode etc. Regardless of which option we select, it then begins booting up for a few seconds, followed by a blue screen which appears for an instant, then it restarts all over again.
I had to film the process to see the information on the blue screen, which states the problem is caused by an UNMOUNTABLE_BOOT_VOLUME, but I can't read any information below this (if there is any) because the my camera isn't quick enough it seems, though I can obviously try again.
Any help is very much appreciated!
