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.
