Hi Pasta948, this is Kimberly, an independent advisor. I'm glad to assist you today.
Thanks for the detailed explanation, that really helps narrow things down. You've already done a lot of the right troubleshooting steps, so the issue may be deeper.
0x80070570 (with Installation Assistant and Windows Update):
Means “The file or directory is corrupted and unreadable.”
0x8007000d - 0x2000c (with ISO):
Means “Windows installation failed in the SAFE_OS phase with an error during APPLY_IMAGE operation”, usually due to missing or corrupted files.
Check TPM and Secure Boot (For Windows 11)
Windows 11 requires:
TPM 2.0
Secure Boot enabled
UEFI (not Legacy BIOS)
To check this:
A. TPM:
Press Win + R, type tpm.msc, press Enter.
Look for "TPM version 2.0"
B. Secure Boot:
Run msinfo32
Look for:
BIOS Mode: UEFI
Secure Boot State: On
If any of these are missing, you’ll need to:
Enable them in BIOS
Update BIOS if needed (visit motherboard/laptop manufacturer's support page).
Should you have more questions, please let me know.
Best regards,
Kimberly
