Regarding the installation of WIN7 on Apple notebooks, in fact, each model is different, and the old one may be fine. However, if the replacement of NVME SSD is involved, and it is not original, you need to upgrade the motherboard BIOS to 10. 13.6 and above, because NVME SSD is not supported below this version. For the 20 13 A 1466 replaced by the author, we used a transfer card with a package fee of more than 20 yuan from a certain treasure, and measured it with SN750 500G solid-state hard disk of Western Digital. The process is also bumpy. Considering that WIN7 has been stopped for a long time, it is unsafe and the software is compatible, we finally installed OSX 10. 15.7 and. If you really need to install WIN7, it is recommended to communicate with the adapter card merchant in advance and choose the appropriate SSD. At the same time, the drivers of BOOTCAMP5.0 and v5 15640 should be downloaded in advance for integration. DISM++ is recommended for integrated drive.
A 1466 keyboard failure when installing WIN7 and entering user name.
As mentioned above, after the installation and deployment of WIN7, the interface keyboard, mouse and touchpad for inputting the user name of this machine cannot be used. The problem here is that the original WIN7 didn't integrate the INTER USB3.0 driver. Before making a boot disk for WIN7 installation in BOOTCAMP under MAC, DISM++ should be used to drive the boot.wim and install.wim two installation image files in the original WIN7 installation image. If necessary, you can also use the original installation image I have made to ensure that nothing is added except the 12 driver file.
When installing WIN7, applessd.sys cannot verify the digital signature when the system restarts. Let's talk about the solution first: Prompt message: The reason why windows can't start may be that the hardware or software file has been changed recently: Windows System32 Drivesapplsd.sys Status: 0xc0000428 Information: Windows can't verify the digital signature of this file. Solution: Insert a USB flash drive with PE (supporting UEFI startup). Hold down the OPTION key, select the U disk to enter PE, delete the file windows System32driveApplsd.sys in the following path under the Windows system partition, then restart to enter Windows, and the installation will continue. The system can be used normally.
The partition format of the hard disk is incorrect and cannot be recognized when installing the system. GPT(GUID) partition format is required.
Installation mode and version of MAC system
The system installation disk must be 10. 13.6 or higher, and it must be formatted into HFS format with TRANSMAC software, and then the DMG image must be restored to the U disk.
Of course, the first choice is the second-hand Apple original hard disk, but it may be slightly expensive or not suitable, so you need to buy a third-party brand at this time. For example, Samsung, Western Digital, Intel, and SanDisk. We used SN750 in Western Digital this time, so far no problems have been found, and we slept normally.
