I have a Compaq Evo N1020v and I tried to reinstall the operating system and now I am getting "Error loading operating system". This is an older computer but it was working fine up to a few days ago. Please help:)

when yo turn the pc on, while the compaq logo is displayed, you should see a msg at the bottom of the screen indicating which key will get you into the bios settings. It should be esc for HP. otherwise try f10, f12 ,f2, f8. It's got to be one of these

hold that key down while you turn the laptop on, before the operating system loads.

Plug the cable VGA in to the compac and the laptop. than go to graphic properties and activate your extended desktop. You can also use the monitor as a second one, or clone

enter 3 times wrong password if it give u a 5 digits code send me that code ill send u password thanks

This is a hardware problem that will require repair. Please contact yor manufacturer for assistance.

Please uninstall all the USB Drivers from the Device Manager and then restart the Computer. The USB Drivers are Operating System generic Drivers. The Computer will reinstall the Drivers for USB automatically

Hi,

Make sure that your CD is Bootable. Now you will need to do settings in BIOS to boot from CD..

1. Power ON the computer and Press "Delete Key" or F1 or F2 or F10 Key to enter in BIOS.
2. Goto Boot Menu Options
3. Select First Boot Device to CD / DVD
4. Second Second Boot Device to HDD
Now Save Settings and exit . it will reboot computer . If your CD is bootable then it will ask to boot from cd message.

Option 2 :
You can try by pressing F12 or F11 key simultaneouslty after power ON computer. It will display Boot Menu so from there you can select "CD/ DVD Drive " and press enter then it will boot from computer.

It will glad to help you further if your problem doesnot get resolved.

Restart your Compaq Evo N1020v laptop without the card inserted. Go into the BIOS (by hitting F10), change the UMA Frame Buffer Size from 32MB to 64MB (located in the Advanced menu), reboot and install the card drivers and insert thecard. This should fix the problem.
