I'm sorry but I still don't fully understand.

When you say that "D boots fine", which operating system boots ?

Did you install two copies of Vista, one on each drive, and were switching between the two by selecting boot priority in BIOS ?

When I flashed my BIOS I had to re-enable RAID in the BIOS in order for my system to boot. Hope this helps.

Vista was only ever installed on C: drive, but somehow after bios update D: has become the system drive in disk management........which is confusing:(

I think I do understand now lol

In disk management, does it tell you that D: is also the boot drive, or not ?

There are in fact three groups of boot files -- the system files that are needed to start the computer, the boot files needed to load the boot environment, and Windows files needed to start Windows.

Usually these three groups are installed to the main hard drive, but it is not impossible (and where Vista is concerned, not rare either) for these files to be split between more than one hard drive -- usually 2, and very rarely 3.

The BIOS update may have created a new low level hard drives configuration, so that the system files are no longer present in the Windows drive.

This is not a problem from a functional point of view, although yes it can be a little confusing.

Bearing that in mind, I would advise you to attempt the following means to try and get all the proper boot files and folder copied properly into C: , so that you can at least attempt to boot from that drive

Quote:

VistaBootPRO v.3.3 Method 8. Open VistaBootPRO and go to the "System Bootloader" screen 9. Select "Windows Vista Bootloader" 10. Select your C: drive Note: Before continuing quit any I/O sensitive applications. 11. Select Force Install and then click on "Install Bootloader" End v.3.3 10. Once done exit VistaBootPRO and reboot your system, selecting to boot from C:

(Adapted from : Windows Vista Boot Problems: Dual Boot Trouble Shooting Guide / Vista Running )

This method should ensure that the Vista boot files are properly copied into your C: drive

Although the information there has been created with dual boot issues in mind, the advice is generally good on how to use VistaBootPRO to resolve boot difficulties

Please note though, that it is possible that D: will remain the system drive, no matter what you do, as the system drive is defined at the low level of BIOS and the Vista pre-boot environment.

Some extra confusion for people used to W9x/Me/XP stems from the fact that Vista can ocasionally order hard drives differently, leading to unfamiliar drives and drive letter configurations, such as on your computer.

No boot is down on C: drive, here whats disk management says:


C: healthy (boot,active,crash dump,primary partition)

D: healthy (system,page file,active,primary partition)

everything seems fine, its just confusing how its done it and if nothing vital will happen i'll leave it alone and stop worrying:P

Yes that's what I thought had happened

Nothing vital will happen, and you can certainly leave it alone and stop worrying

vista can be installed on any drives and its boot files can be on the same drive or any other drives..

in your case , i gather boot files are on d:drives
check ..turn on show hidden files and operating system files and look for a folder name boot(hidden) this is vista boot folder...vista windows files , systems file can be on a differnet drive..i think in your case

windows will boot from the drive u select in bios ..so boot files must be on this drive...in vista case folder boot..

use vistaproboot ohhh sorry to change your boot drive to the drive that contains the boot folder..

try this
