I've been having problems with my computer and so I got things reformatted and It started working. I had this external harddrive I'd been using and hadn't used it for over a month since the reformat but now that I've used the ext. hard drive for the first time last night, in the morning when I went to boot up my Bios settings went wonky like they were before I reformatted and the computer isn't booting properly... This must be because of the external hard drive - for some reason the computer is trying to boot from the ext. hard drive or something. I didn't even have the Hard Drive on when i tried to boot a second time and it still wouldn't boot it was just looking for the hard drive i suppose. Is there some BIOS setting i should turn off in order to prevent this? I also did a system info/diog test with a program called Astra32 and it said: "Warning SMBIOS Information maybe be inaccurate"In the attached picture, it shows the first screen it stopped at when I booted. at this screen i decided to turn on the harddrive and press G to continue but then it brought me to another screen which said: "Veryfing DMI Pool Data ............ Boot From CD : DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER" *edit* I've done a search on this topic and found similar issues with other users but one thing that is unique to my problem is that from the time i first used the hard drive again it's permanently messed my bios and boot settings even if I dont have the HDD plugged in - other members on this forum seem to be able to boot their computer if the hard drive isn't plugged in where is I can't boot whether it is plugged in or not plugged in. I'll be back shortly with pics. Thanks for your time and help guys. *edit2* First Screen that gets stuck on boot up Second Screen if i press g from the prev. screen. My BIOS setup utility screen if I choose to go into it, In order to get there I press delete when my computer first is booting up at the first screen which is some kind of IDE drive bootup thing if i remember right. When i press delete this screen finishes what it is doing then it goes to the screen where i have to press g, then it goes into the BIO set up. Advanced Bios Features menu Hard disk boot priority. Boot Sequence. Now all those previous screens were from when the external hard drive wasn't plugged in... I tried to do a boot up with the hard drive plugged in and everything was the same except the hard disk priority, the next screen is with the hard drive plugged in. http://img443.imageshack.us/my.php?image=dsc06194xe6.jpg *edit* Sorry, actually as it turns out my HDD wasn't plugged in so that picture comparison between the Disk Boot Up priority were both booted without the HDD plugged in. When I did the same test but with it plugged in the USB HDD showed up as a separate USB HDD along with there others - it was placed 3rd in the list between SCSI-1 and Bootable addin cards.
