I recently upgraded my Acer Aspire 4520 laptop from Windows Vista (SP1) to Windows 7 Ultimate.

Everything went smoothly and then when the final restart took place windows 7 was unable to boot, after the motherboard splash screen (the one where you can usually access the BIOS), there is a blank screen with a cursor that just keeps blinking, nothing is loading up.

How can I fix this problem?

Hi there sentinel1,

You need to make sure that the HDD is the first boot device of your system. You can do that when you go to BIOS and just adjust that. Another thing you may want to do is to unplug all USB flash drives, external drives,CDs, etc. Check this out: http://en.kioskea.net/forum/affich-129187-dell-laptop-black-screen-flashing-cursor
If the issue persists, you can try running Windows Repair. Check this tutorial out: http://tips4pc.com/computer-problems/my-computer-boots-up-to-a-black-screen-with-a-flashing-cursor.htm

Hope this will help,

Hey D_Know_WD, thanks for your reply but I did remove all the external devices and I've reset all the boot device settings but still nothing. I have the installation disk however when I try to use the memory diagnostics feature it asks to restart which when I do select it just goes back to the blinking screen.
