Having an about 10 year old i7 machine, I want to re-install Windows 10 Pro over the existing Win10 Education installation using a USB stick. But when booting the Win10 iso, I only get a black screen with blinking cursor. Nothing happens, even not after waiting for a longer time. The used ISO file was generated using Microsofts Media Creation Tool.
Hardware details
- AMIBIOS v02.63 (R01-A2) from 12/09/2008
- Mainboard from Acer aspire m7720
- i7 920 @ 2.66 GHz
Non-working things I already tried
- Easy2Boot
- Rufus with different options (FAT32, NTFS, UEFI, BIOS)
- Re-Download the ISO file
- Using different USB ports (front/back)
- Changing the current boot order temporarily (F12) and permanently using BIOS (ENTF)
- Searching in the BIOS for settings that could affect the boot behavior
- Checking Fix for older BIOS in the extended RUFUS options shows the window logo after booting (instead of black screen) but now it hangs there
- Put the SSD in another pc for installing Win10 and put it back afterwards
- Installing Windows 8.1 with latest updates and upgrade to Win10
Working things
- Use the same USB stick on a newer HP notebook: The Win10 installer starts without any issues
- Also on a non OEM 1366 board (same socket) I can boot and install Win10 easily
- Booting Ubuntu installer from the stick: Works, but sadly I need Win10 for some games
- Flashing Windows 8.1 x64 ISO image from MS with MBR for BIOS
According to the documentation of m7720 we don't have any UEFI here. So MBR for a simple BIOS should be enough and I can't understand why it's not working.
Best Answer
TLDR: Windows 10 contains a bug since months that result in non booting systems and installers when VT-d is enabled in BIOS.
This bug exist since 1803 and altough many users seems to have trouble with it, Microsoft doesn't care about fixing this issue for several months.
What can we do?
Not much. The best thing would be not using Windows, since Windows 10 contains forced updates. So even when you use tricks to install an older release, Microsoft will update it very soon without asking you. When you're in the situation like me that you're forced to use the Windows installation (yet), it seems that you must live without VT-d.
History: How I get to this problem (total about 2 days work)
Found out that it works with older Win10 versions, so it seems that Microsoft break something:
Working
Not working
HeiDoc was quite usefull here, since downloading special versions is a big mess on Microsofts side: The current official Media Creation tool didn't let me choose any parameters about the version. Even when using an older version of the tool itself, it doesn't start and force me to download the latest version.
I tried installing 1709 on USB stick which works perfectly. Since Win10 has forced updates, I'm surprised if the system is working after installing the latest auto-updates, which bring the system up to 1803.
