Dell Optiplex Gx280 not booting Tags: Dell Optiplex Hard Drives Computers Last response: July 17, 2010 8:03 AM in Computer Brands Share samtfaulkner February 23, 2010 7:40:39 PM I bought a Dell optiplex GX280 Small Desktop With no hard drive. It has Pentium 4 HT 2.8GHZ But I have just one question which you may be able to help me with. I have bought a new hard drive for this machine and plugged it in. the bios recognises the HDD. My problem is that i cant install an OS from Cd or usb. I have tried a lot of disks and different OS systems including Win xp, win 7 and Ubuntu. The system comes up with 2 errors. "Selected boot device not available - strike F1..", "invalid system Disk _ Replace the disk then press any key" Ive tried changing the boot order and disabled floppy drive (because i dont have one) in bios would love to get this compy working. Any help or advice would be much apprieciated.

Comes up with "Selected boot device not available - strike F1.." If I make Cd rom the only choice of bootable device then restart with the disks in it comes up with "invalid system Disk _ Replace the disk then press any key" itadakimasu February 24, 2010 1:04:35 PM sounds like the boot sequence is pointing to something other than the cd rom. can you push f2 upon boot and go into bios to check this setting? samtfaulkner February 24, 2010 1:09:36 PM [1 onboard or usb cdrom drive onboard sata hard drive ... ... ] only the first one is enabled at the mo itadakimasu February 24, 2010 3:25:33 PM What disk do you have in the optical drive?

I am having the same issue. I've tried 3 known working bootable CDs with three known working DVD / CD ROM drives. samtfaulkner April 11, 2010 3:24:54 PM no, still not working for me! I tried new Cd Drive, Dvd Drive (internal) hard disk, usb flash drive, usb hard drive; with 3 different working OS systems. Still no luck. Would love to know if anyone can do this?! groo April 15, 2010 4:56:13 PM can you try running the HDDs in different modes? I have 1 stsem were I have to run the Sata drve in IDE mode (or something like that) how about new cables? aford10 April 15, 2010 7:45:38 PM If you didn't try different cables, that would by my first thought. Some BIOS' have a OS install mode. You may need to enable this in the BIOS. Some CD/DVD drives don't read discs as well as others. Try using a few drops of water and a soft cloth to clean the bottom of the discs. dhawes99 April 17, 2010 4:46:50 AM Sometimes the GX280's have motherboard problems, specifically leaky capacitors.
