yes I see what you mean - I just needed clarification so i could compare amongst my experiences,
it is annoyance situation and you can hit DEL and go into BIOS but as you have said but options there are limited
you can use yr installation CD to boot into recovery console
http://support.microsoft.com/kb/314058you may already have looked at options here - boot into CD and choose R for repair at first prompt
you are then asked which installation you want to boot into and you can choose yr current D: drive
you will have access to directories so that you can repair yr Windows
or you can type
help at prompt and choose from a list of commands
use yr installation CD with reference to knowledge base articles in Microsoft Support as in kb article above
also, you will be able to set up yr current D: as Primary, unhook yr backup disk, and run installation CD
so that you can work on just yr system drive
- obviously you would want to repair to boot into this system - but again you might find options limited e.g fixing the boot
you could pas through Recovery console option by pressing Enter instead of R at the first prompt
then pass through eula page (press F8) and go to options at Windows installation page
here you can choose to Repair the current installation
- you will need to have yr current D: drive set up as Local Disk(c:) to do this
- the Windows installation will be repaired and returned to default settings without harming yr documents
- but you will have to bring the system back up to date once again - e.g service packs, internet explorer, maybe drivers, etc...
- run a boot-time scan with avast immediately as viruses survive through Repair installations
you may have tried these options already
if not, then take yr time, and Microsoft Support and google search can be especially helpful in these situations
