Another lesson-learned in seeking dual-boot bliss with Windows 10 Pro that might save someone some time with NTFS disks.
Elsewhere on this forum (How to access NTFS usb drive in Rocky Linux 9) is the trick to adding NTFS so gparted, fdisk, etc. will recognize and list NTFS partitions. However, Rocky would only ‘see’ the internal Windows OS install SSD, but not the internal NTFS data (D:) SSD, which was crucial. Turned out that the SATA mode in BIOS needed to be set to AHCI. As it happens, my Windows OS was installed with the SATA mode RAID capability in BIOS switched ON, and simply booting into BIOS, changing it, and booting back to Windows normally will not reset the loaded drivers and tank the boot (so I was warned, did not try). Changing the SATA setting and booting to Safe Mode will load and reconfigure Win boot, but the bcdedit command was being refused. Also, which speaks to my age, furiously tapping or holding F8 on boot did nothing. Win 10’s boot into safe mode is a bit more buried, but FWIW once in safe mode bcdedit commands work fine. After setting AHCI with no Windows issues, Rocky recognized the second internal SSD. By this time I’d read several takes on configuring mounting the drives during boot for quick access, and aliased the NTFS mounted partitions as C and D for clarity.
If i’d had stumbled accross a similar outine as above to begin with it would have saved me several hours of mostly finding out what I needed to look for. Short version of what worked for me:
- Rocky Linux install on USB drive not recognizing internal NTFS SSDs on Win 10 Pro dual-boot UEFI.
- Get ntfs-3g package from EPEL repository
- Rocky not recognizing second internal NTFS SSD
- Boot Windows 10 into safe mode (search if in doubt how!), in Administrative CMD shell enter:
bcdedit /set {current} safeboot minimal - Reboot to BIOS
- Switch SATA mode to AHCI and reboot to Windows (safe mode boots automatically after grub>Windows)
- In Administrative CMD shell enter:
bcdedit /deletevalue safeboot - Boot to Windows (normally), then reboot to Rocky
- List NTFS drives and partitions noting the names of useful ones
- Mount!
- If desired configure for mount on boot
I hope the above is useful.
