PC will not boot if USB flash drive/HD is connected at time of boot. Any type of usb drive, dvd, ram stick, hdd, will cause it to boot on the usb item and it's driving me nuts, can't leave anything plugged in and boot or re-boot!

No options in Bios to disable this .
Help please.

Someplace in the BIOS is a place to set boot order, you just need to move USB so it comes after HDD and CD.

If not on a tab of it's own, it's usually under Advanced

The user guide for the PC/Motherboard should describe the settings. Download the PDF from the PC/MB maker and search them for "boot order" or "boot sequence". Could be called startup instead of boot as well.

The problem is that even after I reset the order, the order gets changed on booting with the usb device connected! Bios has a mind of its own!

you have to find the correct way to save on your system after you have made the change to the boot order. Some comps dont show the save option clearly

Sometimes connecting at the back works fine and front doesn't.

You can disable USB Legacy support option in bios. Don't do that if you use an USB keyboard and/or mouse.

If your comp doesn't maintain the settings made in the CMOS, it is likely that the CMOS battery has died. Shouldn't cost you more than $5-6 to get a new one to see what happens.
