Troubleshooting guide
How to fix the problem
Linux installer may not see disk due to Intel RST/RAID/VMD controller mode or missing support. A sudden change of mode BIOS can make an already installed Windows unbootable, so prepare data and boot protection first.
Possible solutions
Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.
Installer and driver verification
First, determine where the drive is disappearing.
Steps to follow
- In the BIOS information window, check whether the drive is detected without changing the parameters.
- Note the name of the storage mode: AHCI, RAID, Intel RST, or VMD if provided.
- Check the new supported official Linux installation media and distribution-specific documentation for this controller.
- If the installer clearly warns about RST, stop and read the preparation procedure it gives; do not erase the disc.
Preparing for a safe controller replacement
Only if the manufacturer and distributor allow switching to another mode.
Steps to follow
- In a Windows environment, make a verified copy of your data and save the BitLocker recovery key elsewhere.
- Take a picture of your current BIOS storage mode and make sure you know how to get it back.
- According to your Windows and manufacturer's documentation, prepare AHCI or other provided driver in advance; BIOS switching alone is not enough for all computers.
- After the change, first check Windows startup. Only when it's running, go back to your Linux installation and double-check which drive you're choosing.
If the problem persists
If there is a real RAID array or organization-managed storage, do not change the mode yourself. Provide the installer message, computer model and BIOS storage mode to the technician. If BIOS does not see the drive at all, check the hardware.
