Windows 7: Blinking underscore on Boot-up

Blinking underscore on Boot-up

Hi everyone,

I have an HP laptop that upon boot-up would show the HP logo and then go to a constant blinking underscore on the upper left hand corner.

During the HP logo screen, I pressed f2 to enter "HP Startup" where I scan the hard drive and it passed all the test.

Also I can go into the BIOS by pressing f10. From my research, I changed the order of boot-up and put local hard drive at the very top. I also unplugged the battery. And laptop is still not working.

I also read that perhaps putting in a System Repair Disk might help(?) But I just discover that my cd-rom drive is not working...

Can someone explain to me what would be the best way/ or my options in going about to recovering my data?

Any help much appreciated.

Most likely you have a corrupted file system and need to run chkdsk /r from the Recovery Console. Since you optical drive is not working, you can create a bootable flash drive for Windows 7, see here: USB Windows 7 Installation Key Drive - Create

How to run chkdsk from the Recovery Console
  • Boot your Windows 7 installation DVD
  • When you see "Press any key to boot from CD or DVD", press Enter
  • At the "Language" screen hold the "Shift" key and press the F10 key to open a Command Window
  • For chkdsk, type chkdsk /r and press Enter.

Let this run to completion undisturbed..

If you don't have a install DVD, you can download a legal copy here: Official Windows 7 SP1 ISO from Digital River

Make sure you get the same version you have installed: 32 or 64 bit; Home Premium, Pro or Ultimate.

Hi Ztrucker, thanks for your reply.

I do not have an install DVD so I need to download the ISO file from the link you provided - however, I do not know which 64 bit version of Home, Pro, or Ultimate version Windows 7 I have. How should I proceed from here?

Look on the COA sticker on bottom of laptop for licensed version. If you have more than 4gb RAM I'd use 64 bit.

Work through these steps for Troubleshooting Windows 7 Failure to Boot.
