Windows 7 wont boot without external DVD drive attached

Maybe it's just Acer.

I've an ASUS netbook. I've installed Win 7 via external DVD and also installed Win 7 (after wiping clean) via UFD (usb flash drive==usb stick)

System always booted correctly after either install method.

OK thanks guys (and girls perhaps!)

I'll try all your suggestions tomorrow as I'm offline from now. Just one thing, how do I system repair. When I put the upgrade disc in mid week it just took me straight to the install option. Do I have to boot with the disk in? Will that give me the repair option?

Thank so far, I'll let you know how I get on tomorrow! I hope

Make a system repair disk. Boot from the system repair disk.


CREATE A SYSTEM REPAIR DISK
START | type System Repair | Enter key | Create Disk button

I have an Acer Revo and installed my free Windows 7 upgrade disc one week ago with an external DVD drive. The install went swimmingly and no problems were apparent.

I removed my Samsung external DVD drive when finished and all was well. However, when I turned on the Revo the next day, Windows 7 would only get as far as the splash screen and then hung with a blank screen.

If I space bar, the cursor works, I get a blue windows screen (at a diff aspect ratio to the screen) and right click works which gives me some options (but nothing that allows me to kick start the process). There are no user options and no desktop items. I have checked that view is set correctly etc.

I have tried Ctrl Alt Del which just kills the blue screen and mouse/cursor movement.

My only option at this point is to hard shutdown.

HOWEVER, if I plug in the external DVD drive, it will boot normally and work fine.

I have entered te BIOS and changed the order of boot, to no avail.

It will also revert to this dormant screen if it goes into sleep mode.

My work around has been to set sleep to NEVER and keep the external plugged in, but that defeats the object of buying the REVO.

I have searched the internet for a solution, but so far, no luck.

I tried updating the NVIDIA driver but that would not install properly.

Any ideas anyone? Please???

I'm guessing you already tried the obvious...
Right click on the DVD drive's icon and eject it....
