Windows 7 blank screen after bootloader

have a Dell Inspirion 1525 with Windows 7 RC dual booting with MacOS 10.5.8 on two separate partitions on one 160GB drive.

Windows 7 has been running great since installing on release day, this morning after i turned my laptop on, i got to the Windows bootloader, selected Windows 7, it then goes to a blank screen with the hard drive light constantly on. left it for about 10 minutes, nothing.

my MacOS install on the second partition still works 100%.

i tried a few things, startup repair from the Win 7 install DVD, it sees my Win 7 install on C: but gave an error saying it couldn't fix, the error report mentioned something about "startuprepairoffline" & "NoOSinstalled".

then tried a system restore from the disk, says it couldn't find any restore points (?!)

then tried to fix the mbr via recovery console, says it did the fix, but still won't boot.

ran out of ideas!

any help will be GREATLY appreciated!

What boot loader are you using?

When you get the black screen is there a cursor in the middle of the screen

no cursor, nothing, just a blank screen. the bootloader is the standard Microsoft bootloader.

Can you click Alt-Ctl=Del keys and wgat happens? Doos it bring up TaskManager?
