I bought a second hand desktop that didn't come with any windows install... I am trying to install from USB right now but for some absolutely unknown reason when I boot from the USB it comes up with a black screen saying "Disk error, press any key to restart"

 

As far as I know the USB flash drive is working fine... And so are my USB ports. The only thing I can think of is that it could be related to the harddrive inside the computer, OR it could be some other hardware related problem. Any ideas? I'm going crazy here :(

 

The comptuer is a Dell 755

 Did you tap F12 to get the boot menu and then select the USB flash drive. What utility did you use to put the install of the OS on the flash drive? What OS is on the USB flash drive?

 

Tapping F12 will also give you access to the Dell Diagnostics if the partition is still intact.

If I remember correctly it wasn't showing USB device on the boot options so I went into the bios and set it as the first boot device. When it boots the USB stick flashes but then error.

 

I installed windows 7 onto the stick with wintoflash software.

I also tried running the dell diagnostics. No problems.

Can you boot using the Windows 7 install disk? If you have the Windows 7 iso use Rufus to create the bootable USB flash drive. I think the OS on the flash drive is not detected and then goes to the next boot device, the HDD, and that is why you get the error.

 

Run Rufus and select MBR as the Partition scheme. Leave everything as default. In the Dropdown box that shows Freedos select iso image and click the icon next to it. Browse to the iso file and press Start. Any data on the drive will be deleted.

Well in the case that I don't insert the USB stick at all I get a different error so I don't think it is just skipping it.... Anyway I will try with Rufus now and see what happens.

What is the error that you get when you do not have a USB flash drive attached?
