So my Vaio laptop has crashed. I REALLY need to recover my files, and I'm unwilling to use a data recovery service that will cost me $150 - $1500 (as quoted by a Best Buy rep). I am attempting to boot Ubuntu off a CD, flash drive and external hard drive, so that I can access my files, but none work, even if I change the boot order in setup. Instead I get the "Windows did not start sucessfully... start in safe mode, etc." message, after which the blue screen of death appears for a millisecond and then the computer automatically reboots. The model is VGN SZ230P; I got the laptop 2 years ago, and it runs Windows XP SP2, I believe, which was already installed when I bought the computer. If i exclude my internal hard drive completely from the boot order, it says operating system not found. Help?
