How to delete all partitions in windows 11?

GParted Live is likely your best option if you are going to delete partitions on Windows 11. GParted is a powerful, open-source partition editor that runs entirely outside of Windows.

Why it fits your request:

✅ Best: Most Windows users have never heard of it

✅ Completely free: Open-source, no paywalls, no ads

✅ Bypasses Windows completely: Boots from a USB drive, so it can delete any and all partitions (including the ones Windows protects)

✅ Thorough: Can delete EVERY partition on your SSD, leaving it completely raw/unallocated

What you'll need: An 8GB+ USB flash drive and another computer to create the bootable drive.

Step-by-step to delete partitions on Windows 11:

1. Download GParted Live. The file is about 400-500MB.

2. Create a bootable USB:

• Select the downloaded GParted ISO file
• Write it to your USB drive

3. Boot your ProBook 650 G5 from the USB:

• Insert the USB drive
• Restart and press F9 repeatedly (HP's boot menu key)
• Select the USB drive from the list

4. Use GParted to delete ALL partitions:

• GParted will start in live mode (no installation needed)
• You'll see a graphical interface showing your 512GB SSD with all 5 partitions
• For each partition: Right-click and select "Delete"
• After marking all for deletion, click the green checkmark ("Apply All Operations")
• Confirm when prompted

5. Result: Your SSD will now show as one large block of "unallocated" space—completely clean.
