Installation failed to start Windows 10 UEFI version.
Installation failed to start Windows 10 UEFI version.
Initially I attempted to set up another operating system on the disk, but it wouldn't boot in UEFI. I then tried erasing the drive and installing Windows 10 to test if it would boot from the disk, though the laptop still refuses to accept a boot attempt. I’m unsure why this particular disk isn’t working at all. I have another SSD running Windows 10 that boots fine in UEFI, so something must be wrong. My Toshiba Portege R930 is the model in question. Please share more details if you can. Thank you! P.S.: I have a snapshot of my disk management showing the 120GB SSD is completely non-bootable while the 256GB works perfectly.
Yes, it seems like none of the information about the 120gb matters. You're okay with losing everything.
You should boot into the operating system that comes with the 120GB SSD, ensuring it loads correctly and functions as expected.
Did you really mean to ask this? As noted, I just set up a new Windows 10 on the SSD and can't boot from it. Now what would you say? If it's not clear enough, I’m sure you’re right—I can confirm that when installing Windows 10 into the 120GB SSD, the 256GB one isn’t connected at all. Only one drive is linked to the laptop at any time, and the EFI partition is visible on the 120GB SSD.
Begin by launching Start, enter CMD, right-click CMD.exe and select Run As Administrator. Proceed to input commands one by one, pressing Enter after each Diskpart Select Disk 0 Clean Exit command. Remember, this is based on the screenshot you provided; ensure your 120gb drive remains listed as Disk 0 in Disk Management before running the clean command. Clearing the wrong drive will erase it and lose data. You're warned. Next, power off the laptop and disconnect the 250gb drive completely. Launch Windows Setup using your installation media. On the partition screen, click next without assigning any partitions. Complete the setup as usual. The laptop should now boot from the 120gb drive. If it doesn't respond again, we'll review the UEFI settings.
I acknowledge that I followed the instructions you provided before starting this discussion. Thank you for your work, my friend—I really appreciate it.
