Hi Eddie Does IT,
Thanks for reaching out! This issue with the Surface Pro model 1824 not booting from USB after using diskpart has come up for several users, and there are a few reliable fixes you can try. First, make sure you're using the official Surface recovery image from Microsoft’s Surface Recovery page, as generic Windows ISOs often don’t work well with Surface devices. For the USB drive, use a 16GB or 32GB stick formatted to FAT32, larger drives may fail unless formatted with third-party tools. If your ISO is over 4GB, you can use Rufus to format the USB as NTFS and enable UEFI (non-CSM).
Also, check your UEFI settings by holding Volume Down + Power: disable Secure Boot, enable USB Boot, and set USB as the first boot device. Some users also had success by swiping left on the USB boot option in BIOS to trigger boot.
If you're prompted for a BitLocker recovery key, make sure you're signed in to the correct Microsoft account when retrieving it from account.microsoft.com/devices/recoverykey.
Let me know if you need help with any of these steps, happy to assist!
Best,
Carl
