To completely reset your HP Mini 600 G4 and remove all traces of BitLocker, Windows, and old partitions.
To completely reset your HP Mini 600 G4 and remove all traces of BitLocker, Windows, and old partitions, you can fully wipe the internal drive using a Live Ubuntu USB.
This will remove:
- BitLocker encryption
- Hidden recovery partitions
- Windows bootloaders
- Any bad UEFI/MBR setups
⚠️ Warning
This process erases everything on the internal drive. Be absolutely sure you don’t need any data from the device.
✅ Steps to Fully Wipe and Install Ubuntu Cleanly
1. Boot into Ubuntu Live USB
- Insert your Ubuntu USB stick.
- Power on the machine and hit
Esc, thenF9to select the boot device. - Choose your USB and select “Try Ubuntu”.
2. Open Terminal and Identify the Internal Drive
Type:
sudo fdisk -l
You’re looking for something like:
/dev/nvme0n1→ NVMe drive (common on newer machines)/dev/sda→ SATA SSD
DO NOT wipe your USB stick — confirm which is the internal drive.
3. Completely Wipe the Drive (Including BitLocker and GPT Table)
Replace /dev/nvme0n1 with your internal drive identifier:
sudo wipefs -a /dev/nvme0n1
sudo dd if=/dev/zero of=/dev/nvme0n1 bs=1M count=100
This removes:
- All partitions
- BitLocker headers
- EFI bootloaders
- Partition tables (MBR/GPT)
4. Reboot into Ubuntu Installer
- Restart the computer.
- Boot from the same USB.
- This time choose “Install Ubuntu”.
5. Install Ubuntu With “Erase Disk” Option
During the Ubuntu installation:
- Choose:
Erase disk and install Ubuntu - It will now create a fresh GPT and appropriate EFI partition.
- Let it install normally.
6. Check BIOS Boot Settings
After installation:
- Reboot and press
Esc>F10for BIOS. - Under Boot Options:
- Ensure UEFI Boot is enabled.
- Ensure the internal disk (e.g., Ubuntu or the drive model) is listed as a boot option.
- Disable Secure Boot for now (Ubuntu supports it, but better to test without first).
- Save and exit.
Once done, your machine should boot directly into Ubuntu with no trace of BitLocker or Windows.
