You need to use the F-key -'select boot device' (wording may vary) option and then select the UEFI: xxxx option that corresponds to your usb drive.
Once you boot the uefi option windows should see your Hitachi (which I assume also had windows on it and you are reinstalling or upgrading)
Uefi is a secure bios and wont let you see 'unauthoriszed' drives.
That's not been my issue, here are the steps I am taking:
I hit Esc to bring up the "Please select boot device:" menu. Option I choose is UEFI: USB 2.0 USB Flash Drive 1100
It takes a while to load the installation setup. I choose the languages (English), Time (English US) and Keyboard input (US). I then can choose Install now or Repair your computer. I choose Install now.
Setup starts and runs for a few. I agree to the license terms. I then have to chose what installation do I want, upgrade or custom. I choose Custom: Install Windows Only.
This is where I hit the brick wall. The "Where do you want to install Windows?" screen comes up and I get an error stating "We couldn't find any drives. To get a storage driver, click Load driver".
I have spent hours trying drivers to no avail. It's an Intel Core I3 so I tried all the Intel drivers I can find. (Tried a few AMD too just for posterity) Went to the ASUS website, they recommended Intel_RAID_Win7-8-8-1_V13101058. This had multiple drivers contained within. ALL failed.
It just never sees the drive. I'm stumped. I want to do a reinstall because the version of 8.1 64bit on there now is a mess. It locks up and its very slow. So I dont think the HDD is damaged because the OS loads when I dont force it to boot to USB. And I got the drive information from the BIOS.
Serial ATA Port 0
Device Type: Hard Disk
Model Name: Hitachi HTS545050A7E380
Serial Number : blahblahblahblahblah
So the system sees the drive, it has an existing OS on it that while corrupted, infected or compromised, is bootable. So I dont have any inclination it's a hardware issue with the actual physical drive.
Also I have tried this with all types of BIOS options changed.
Secure Boot Control (Enabled and Disabled)
Launch CMS (Enabled and Disabled)
SATA Mode Selection (AHCI and IDE)
I cannot find any driver to load that gets the Windows 8.1 install to recognize it.
