|Give your brother a good slap for a start (why did he suggest throwing away the recovery disk???)|
Anyway, can you get to the 'safe mode' screen? (tap F8 as the computer is booting) & is there an option to 'repair my computer'? - if so try that. If not, do a Google for 'Vista Recovery Disk' - there were a couple of sites that had the iso for this - it's a disk you can boot from & fix start-up problems.
Unfortunately I can't find out a lot about the error message you're getting. I take it that the 'System Recovery' you mention is not an option? If you need to recover data beforehand then a live Linux disk (Ubuntu or Kaspersky Rescue) are good options, then, depending on the make of your computer - whether it's an OEM system, for example, then a reinstall may be the simplest option.
