Hello, I've troubles with Windows 7 on a new laptop. It installs fine, but after the first restart I got BSOD: "The BIOS in this system is not fully ACPI compliant"... 0x000000A5 (0x00000011, 0x00000008...)" When I hit F8 to enter "Safe mode with command prompt" when Win7 is starting (just before the BSOD) it loads some drivers and then stops at disk.sys. The laptop is Y530 Legion Lenovo - H370 MB with i5-8300h, GeForce1050ti, Intel SATA 3 SSD (8086&A353). BIOS settings: Boot Mode: Legacy Support Fast Boot: Disabled USB Legacy: Enabled What was done: I. Got Windows 7 install.wim. DISM these drivers into all it's images (and into winre): 1. Intel-Serial-IO-Driver for Win7 (ACPI TIME, Gaussian Mixture, LPSS, Managemen Engine, Serial IO, Thermal) 2. pure 64 bit Win7 Intel USB 3.0+3.1 Drivers v5.0.4.43 WHQL with DPinst option 3. Universal 64bit Intel RSTeAHCI+RAID drivers v15.9.8.1050 mod+signed by Fernando II. Unpack Windows10.iso. 1. Replace Win10 install.wim with the updated Win7 install.wim. 2. Repack Windows10.iso. III. Write the image onto a 16GB USB flash drive with Rufus: 1. Partition scheme: MBR; Target system BIOS 2. File system: NTFS Tools like 7UPDATERv54 and Windows_7_Image_Updater were also tried resulting in BSOD.
