Setting up Windows assistance needed.
Setting up Windows assistance needed.
So a few weeks ago I attempted to set up Windows 7 on my Windows 10 PC. There was an error message saying "some sort of issue" and it wouldn’t install, especially since Windows 10 had already been reset. I ended up without an operating system. When I tried reinstalling Windows 10 I ran into problems with GPT and MBR partitions. I’ve been unable to get the PC running since then—I can’t boot or use anything. I’m trying to install it from a HDD by creating a bootable drive, but even USB attempts fail. I’ve also considered cloning my laptop’s hard drive (it doesn’t boot) and converting to GPT or MBR. I’m really stuck and am considering taking it to a repair shop for installation. Any suggestions or ideas would be helpful.
During the Windows 10 setup, remove the existing partitions if needed. If that fails, try using a Linux USB or CD to erase the drive.
Consider a Linux live USB and apply GParted to erase the drive. Alternatively, you can visit the website for partition management guides or try DBA, as it writes zeros which might slow the process.
Install from DVD or USB only; HDD connections won’t help. Use a 4GB flash drive and run the media creation tool to build your installer. Disconnect any other hard drives, keeping just the Windows drive connected. Start in UEFI, turn off CSM (Compatibility Support Module), enable fast boot and secure boot. When you launch the Windows 10 installer, on the partition screen press Shift+F10 and enter the commands one by one (press Enter after each). Use Diskpart to select disk 0, clean and convert GPT, then close the window and try again—it should succeed.
