Question No POST, BIOS and video output after SSD. Reinstalling HDD fixes everything.
Question No POST, BIOS and video output after SSD. Reinstalling HDD fixes everything.
I own an older HP EliteDesk 800 G1 USDT model, equipped with Intel i5 vPro processor, 4GB RAM, and a motherboard from HP 18E5.
I bought a Lexar NS100 256GB SSD.
Last night I attempted to clone the existing HDD using Macrium Reflect, but the process halted after 90%, leading me to suspect the current hard drive is faulty. To resolve this, I made a Windows USB flash drive for a clean flash operation.
The issue arose when I swapped the HDD for the SSD: the PC failed to POST, entered BIOS, and displayed only a black screen without any video output.
I’ve verified all connections are secure—nothing is missing. In fact, reinstalling the HDD resolved everything; it boots normally on the USB drive, OS, and everything functions correctly.
The SSD appears to be functioning properly at least, though it shouldn’t be. When connected via a SATA adapter, it operates without problems. It’s in GPT format with no partitions.
Any assistance would be greatly appreciated.
PS: I should note that during the initial installation of the SSD, I booted into BIOS by pressing F10, as I had set the USB drive as the boot order for Windows installation. That attempt failed (black screen), so I restarted and then encountered this problem.
Welcome to the forums, newcomer!
Using Macrium Reflect but the process halted at 90%,
Your clone wasn’t completed properly or you had to wait a bit longer until it reached 100%.
I set up a Windows USB Flash Drive for a clean flash.
Do you mean a fresh installation? You’re updating the BIOS, treating it like firmware. Then reinstalling the OS, since the OS is software.

Is secure boot or TPM enabled in your prebuilt system?
It wasn’t working (black screen), so I restarted it and then this occurred.
Attempt to clear the CMOS without the SSD, boot from the HDD, and back up any mission-critical data from it. Then power down and replace the HDD with the SSD to see if you can reinstall the OS onto that SSD.
Hi, thank you for your message.

Sorry, it got stuck at 90% and then an error 0 appeared.
Are you referring to a clean installation? You would need to flash the BIOS with an update (since BIOS is firmware). You should reinstall the OS (as the OS is software).
- I understand you want to build a Windows 10 installer tool using a USB drive, and then set it as the first boot option in BIOS.
Is secure boot or TPM enabled on your prebuilt system?
- Secure boot is turned off.
Updating the BIOS seems possible. The BIOS version is 2013, while the latest is 2017. I tried using HP Bios Installer (similar to yours) but it didn't work after loading.
I’m also curious if this PC might not support certain SSDs, including the Lexar model, since some brands like Crucial are fully compatible. I don’t understand how it booted into BIOS the first time.
