Hi!

Recently I created a Ubuntu install on USB. All by the rules (http://blogs.zdnet.com/hardware/?p=1873)!
PC should startup under windows as always if no usb-stick avalable and from Ubuntu with the stick installed.

However! The Ubuntu usb-install has changed either the bios or the MBR (or both) because the PC doesn't boot anymore if the usb stick is not connected. In this case the screens show the "famous" ERROR 17 or ERROR 21 after the line "GRUB loading stage 1.5". I even cannot access the bios-menu.
If the stick is connected, a menu appears (after being loaded from the usb stick) which gives the choices of several Ubuntu setups or the Windows XP Prof install.
After this, Windows starts up as it always did and I can remove the usb stick.

I want my original Windows startup back! :( without the necessity of putting the usb stick in.


I wonder what to do?
1. reload the bios, but I don't have a floppy drive
2. ask Toshibe to send me the CD with the original Windows XP Prof, in order to repair the MBR
3. get and run mbrwiz.exe and try to repair the mbr myself; but I don't know the original mbr-settings

hardware involved: Toshiba Tecra A3 (nov 2005)

Anyone familiar with he problem??
