I don’t know what have you done exactly but fact is that HDD recovery installation (F8) works with factory settings only.
Generally speaking you should be able to access “Advanced boot options” using F8 at start-up. If “Repair my computer” option will be there is other thing.
If you cannot access recovery image using F8 you must use recovery disc for OS installation. Have you created this disc following Toshiba instructions?
The machine did something and stuck. Tried my own Win7 64 Ultimate DVD.
What have you tried and what happen exactly?
