Issues during setup of Windows 10 installation.
You're facing a common issue when upgrading after hardware changes. The message indicates your system is using an MBR (Master Boot Record) and needs a GPT (GUID Partition Table) disk for a clean install. Since you're installing Windows on an SSD or similar, ensure the drive is properly recognized and formatted. Check if the SSD supports GPT and consider formatting it as a GPT disk before reinstalling. If unsure, consult your hardware manufacturer's support for guidance.
Please choose the disk, then tap delete at the bottom, proceed to the next step and continue the installation.
I restructured it for the same drive, hoping it would function without much loss. There were unexpected partitions appearing, making it hard to tell what they are. I'm focusing on installing on the blue one and don’t want to wipe too much data. The others on Partition 4: Data seem unfamiliar.
The installation you're attempting is not on a properly formatted partition. Approximately half of it is already occupied.
Consider transferring the data from the existing drive partition to a clean slate before reformatting.
However, I changed the format earlier to get Windows running, and when I reinstall it, the OS just indicates something is present and asks if you want to erase it. The issue is that it won’t let me choose it initially. Should I move everything off the drive and remove all partitions before creating new ones?
Based on my past experience with setting up Windows, I always needed to completely format the storage drive. I would transfer all the important files—photos, music, and valuable documents—and then perform the full formatting process. However, I should consider getting input from others before doing this, as I’m not fully confident in my decisions.
Well, that's clear now. Change your BIOS from legacy to UEFI. Clean the HDD or SSD, and remove the old MBR or GPT partition table. Select all partitions you plan to install Windows on, delete them, then create a new partition—Windows will likely add extra ones for booting and recovery. Make sure you back up everything before proceeding, as it won’t be recoverable once done.
