Cannot Boot From Any Device in User to User Help Posted August 20, 2010 · Edited August 20, 2010 by dragnmastr85 You will need to look into the boot options in the bios to check the boot order, Removing the cmos battery from the motherboard, will often reset the bios. You will need to reset the date/time if you do this' If you leave a usb device that will not boot and if the bios is set up to look for a usb device first before the hard drive, you will see a boot failure error. Be sure all usb devices are disconnected, including any printers Sorry I thought I mentioned I have already checked the boot order. This is a netbook so getting to the cmos battery will not happen Flashing the bios would have had the same effect, however, and that didnt help. The only USB devices I have been using are bootable ones. Update: the new linux live usb drive works! So I guess it was just the MBR getting screwed somehow and the usb drive going at the same time. Very strange. I will try to recover the MBR through linux. Ill post back. Update: I installed linux where I intended to in the first place and grub fixed the MBR on its own. Sorry for doubting you. The symptoms I had pointed to no bootable devices working. But it turned out to just be a flash drive and the MBR going to at once. Thanks!
