Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:
- Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
- Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
- Step 3 : Click “Repair All” to fix all issues.
Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.
Wally’s Answer: Reinstalling Windows can be a real chore at times, especially when facing problems. Many users have been encountering problems when installing Windows 7 on a Windows 8 (or Windows 10) computer. Here, we will look at how to fix these problems.
The user can’t install Windows 7 on a Windows 8 (or Windows 10) PC (or Laptop) computer.
The most likely cause is that the Windows 8 (or Windows 10) computer has a GPT partition system instead of MBR.
Here are some ways to fix this problem:
What The Heck are GPT and MBR?
GPT and MBR are two different ways of storing partition information on the hard disk. When you make a new partition, you can choose to make an MBR or GPT partition.
MBR can only work with hard disks of size up to 4 TB. MBR was the standard on all Windows PCs, until..
GPT (GUID Partition Table) became the new standard for Windows PCs and Laptops. As for the limits of GPT, they depend mostly on what Windows will allow. GPT has much better protection against hard disk corruption.
You Will Need To Convert Your Drive
If you must install Windows 7 on your Windows 8 (or Windows 10) computer, then you’ll have to remove all partitions and make GPT partitions. Use the diskpart command as explained in this article. You can also delete old partitions and make new ones using a free third-party tool like minitools Partition Manager if using commands is too difficult.
Copy Important Data before Converting Partitions
You should copy important data before deleting all partitions and converting the hard disk to GPT. You can do this even if Windows is no longer working normally. Follow the instructions in this video to make a bootable Linux USB. Use it to copy all important data easily.
