Dear Sirs,
I have a laptop called Asus XMA 200, 11 inches. It came with 2GB of DDR3 1333MHz RAM soldered, which means that this RAM cannot be upgraded.
So, Windows 10 will be very slow on this laptop. Therefore, I decided to install Windows 7 on it.
I burned Windows 7 x64 1706 ISO onto a flash drive, then I booted from it, and guess what? The laptop showed me (Photo 1️⃣).
I tried everything I could:
· Disabling Launch CSM
· Re-enabling Launch CSM
· Enabling IDE Mode (the storage is an HDD)
· Turning off Secure Mode in the BIOS
I did everything in the BIOS.
First, I suspected the storage drivers, so I went to Dell Support and searched for an Intel Rapid Storage Technology F6 Driver. I downloaded the file (DRVR_SATA_Intel_A01_H79NK_f6flpy-x64-setup_ZPE.exe), copied it onto another flash drive, and installed the drivers, but as I expected, they were useless.
After that, I got tired, so I removed all power sources, then removed the HDD and put it into another laptop (MSI Megabook GX 700 X) and installed Windows 7 on that hard drive. It was very easy to install it on the other laptop.
When Windows 7 was fully installed, the laptop restarted, but before it booted from the hard drive (when the MSI logo appeared), I turned the laptop off, ejected the HDD, and put it back into the Asus XMA 200 11-inch.
The laptop started the BIOS, and it didn't detect the HDD. I put back the Windows 7 installation flash drive, but the problem wasn't solved.
What should I do?
