I have a DELL Optiplex GX260 Series, and umm i cant access my bios settings, F2 gives me the setup and F12 the Boot Menu. There are no advance settings in my setup as well. I have searched everywhere and I cant seem to rectify this problem. Please HELP!!

I need to install Windows XP on my desktop, my CD-ROM does not working so I am using a USB drive for installation and i need to change my Bios Boot settings. So I really need the BIOS settings, any ideas? And oh i tried Pressing DELETE as well, didn't work.

You should turn legacy usb support on. Use one of the front usb ports and F12 should be sufficient to select your USB drive. – VMai May 18 '14 at 17:34
Legacy usb support? Whats that? By the way I am using the front port, I have my USB inserted there! – alexhilton May 18 '14 at 17:35
The title states you can't access the BIOS, but you also say "F2 gives me the setup". Can you enter the BIOS or not? – brack May 18 '14 at 17:42
I enter the system setup, and I cant seem to find any option to enter into the BIOS settings. – alexhilton May 18 '14 at 17:43
Also, have you updated your BIOS? If not I would try that as per:… – brack May 18 '14 at 17:45

At there's a section that says:

HDD Priority

HDD (default)
USB Device

NOTE: To boot from a USB memory device, select the USB device and move it to make it the first device.

I think that might be what you need to find and do.

@brack I tried your suggestion and updated my BIOS and as chuck suggested, yep I got the USB Device option in my BOOT MENU but when i tried to boot from it i got this error saying that NTLDR is missing so I am trying to figure out another issue here. It never stops. – alexhilton May 18 '14 at 18:17
