Installing Windows 10 for the first time, avoiding previous attempts.
Installing Windows 10 for the first time, avoiding previous attempts.
Hi, I understand your concern. You're experiencing a situation where Windows 10 initially didn't recognize the HDD partition after formatting, but later recognized it during a second installation. This behavior might be related to how the operating system handles partition recognition in UEFI. It seems like the system is trying to remember or reconfigure the partitions, which can happen during subsequent updates.
You might need to explain your steps carefully. I'm not sure exactly how you were led to this problem, but I can summarize: uEFI reads the GPT or MBR partition that is stored on the disk. If Windows detected a prior installation, one of those disks might not have been formatted properly. Generally, disconnect all drives except one during a fresh installation to ensure Windows places all required partitions on the same drive. This helps avoid them being scattered across multiple disks.
For better clarity, you don't need to format all drives during OS installation. Just focus on the specific drive where you want to install the operating system. If you already have Windows installed, you might not need to format it again. The issue likely came from a failed partitioning and letter assignment, which could have been resolved through disk management.
