I just bought a new ASUS laptop with 1 SSD and 1 HDD. First, I installed Ubuntu 17.10 on SSD, but it couldn't start (with TSC_DEADLINE disabled due to errata
message), so format everything and install Window10 on SSD instead.
Everything worked just fine so I decided to install Ubuntu 17.10 again. I googled and found a solution to TSC_DEADLINE disabled due to errata
message, by updating BIOS from ASUS support site. (But I have not installed Ubuntu yet)
After finished the update I start my laptop again and it directed me to the BIOS setting menu, which has no drive on it (not found SSD and HDD).
I found that I should go to System Configuration > SATA Operation and select AHCI.
and restart. Then both SSD and HDD are found in the menu. Then I boot it with SSD (which has only Windows10 installed), but it directed me to this page:
error: unknown filesystem.
Entering rescue mode...
grub rescue>
So I restart and try booting with the HDD (which has no OS in it), and the Windows 10 started unexpectedly. In This PC
menu in Windows 10 shows that Windows 10 is installed on SDD (which is correct).
It seemed like my laptop switch the HDD and SSD, how can I fix it?
For summary:
- I installed Ubuntu 17.10 on SSD and couldn't open it
- I formatted and installed Windows 10 on SSD instead
- I updated my ASUS BIOS and change SATA Operation to AHCI
- The HDD and SSD are switched
- I booted with SSD (which has Windows 10) and the directed me to grub rescue
- I booted with HDD (which has no OS) and the Windows 10 is booted
Edited: I used MBR on my HDD
Did you use MBR or GPT on the HDD? Update the question, do not reply supply the information, in a comment. – Ramhound – 2017-11-07T14:57:22.217
