My personal PC was working fine until I tried to test-boot a bootstick I built for field use.
Now, if turned on and left alone to come up, this PC will post and stop with the message, "insert boot media". Now I must go to the BIOS and scroll down to select the boot vol, to have the thing come up to Windows 7 pro properly.
I am a traveling technician that supports Hewlett Packard mobile and desktop units. HP has a procedure for installing the serial number into a replaced motherboard using a boot stick for that purpose. After power up of a laptop and choosing the bootstick device, I am supposed to get to a window that asks to populate fields with serial number and other data. This seems to work on the refurb motherboards supplied for replacement.
However, if the mobo UUID is not some correct value, the mobo is considered ‘locked’ and I must boot with the second stick to a file called “ SMC.bin”, to clear the UUID. For background, I will include the boot procedure for this stick: “Hold the logo key and the up-and-down arrow keys and power on....release when HP logo appears”
A 2 gig stick (which is the subject of this issue) was formatted FAT and the SMC.bin file was copied to the root. I booted my desk PC with it to see if it was recognized. A white window with black lettering appeared asking to choose between three options. I took no action and shut down the unit, and withdrew the stick. At next boot, the same window appeared, as though the stick was still in place. The window appeared several times, and I had to go to BIOS to choose the standard boot volume for normal ops. If I did not go to bios and choose the boot drive, the boot message comes up giving the three options (do not remember what they were).
The message has since changed to ‘insert bootable disk’. At one point, MBR appeared in the message but has gone away.
Has this ‘boot file’ or part of it been placed on the boot volume? Why does the pointer go to this code and not the windows loader? How shall I look for it?
I do not believe system restore will help, because this code seems to exist on the boot vol apart from Windows.
Thanks for your assistance.
