Clean Unallocated Space for Windows | Generated by AI
Question: Used Setup’s own “Delete Partition” to remove the 476GB partition on Disk 0, now it shows as unallocated space — what next?
Answer: Good, that’s the simplest path and it worked. From here:
- Select the unallocated space on Disk 0.
- Click Next directly — do NOT manually create a partition first. Windows Setup will auto-create the 4 partitions it needs (Recovery, EFI System, MSR, and the actual Windows partition) when you let it work with raw unallocated space on a GPT disk.
- If you manually hit Create Partition yourself instead, Setup will only make one partition and you’ll have to deal with the EFI/MSR partitions separately — just let it auto-split.
If Next now proceeds without the “unrecognized type / offline” error, you’re clear — that error was tied to the old Linux Mint partition signature (LVM/RAID metadata) on that specific partition, and deleting it wiped the metadata that was confusing Windows’s disk driver.
One thing to check: your photo showed two disks, each with two partitions (Disk 0 and Disk 1). If Disk 1 also has leftover Mint partitions (e.g. a separate /home partition or swap), and you plan to install Windows fresh with no dual-boot, you may want to delete those too now to avoid leftover Linux partitions cluttering Disk Management later. If you want to keep Mint on Disk 1 for dual-boot, leave it alone — Windows Setup won’t touch other disks unless you select them.
