Hi, Lee.
Easy question first...The default setting for what to do in case of System
Failure is to Automatically restart. So, when the BSOD appears, the
computer immediately reboots before there is time to read the screen. One
of the first things I do when installing Windows is to change that default!
Go to System Properties | Advanced System Settings (you'll need
Administrator credentials for this) | Advanced | Startup and Recovery /
Settings. Then just UNcheck the Automatically restart box. Next time, the
BSOD will stay onscreen until YOU push the Reset button, giving you all the
time you need to read it and copy down the Stop Code and other information
there.
Now to the drive letters: These shift like drifting sands when we reboot to
a different Windows installation. So it's best to give each volume a NAME
(a label), which will be written to the disk and will not change when we
reboot from Vista to Win7 and back. As Carlos said, Vista changed from the
WinXP method of assigning drive letters at Setup.
When we boot from the DVD to run Setup, it has no idea what letters may
already have been assigned, so it starts by assigning C: to its own Boot
Volume (which is NOT what most of us think of as the boot volume! See KB
314470.), which might be the 3rd partition on the second HDD. Then it
assigns the next letter (D:, unless we are installing into the System
Partition) to the System Volume, typically the first partition on the first
HDD and traditionally thought of as Drive C:. No matter which partition we
choose to install Windows into, the few updated startup files must always be
in the System Partition - and Windows doesn't care what its drive letter
might be.
To preserve Vista's existing drive letters, we must boot into Vista and then
insert the Win7 DVD and run Setup from there so that it can "see" and
inherit the existing letters. Later, of course, we can use Disk Management
to change any of the drive letters EXCEPT the Boot and System Volumes; the
only way to change these is to run Setup again - that is, to reinstall
Windows.
To see which drives have which letters and which status (Boot, System, etc.)
in EACH OS, boot into each and run Disk Management (diskmgmt.msc).
