What's wrong with my PC?
1. I can Not install Ubuntu18.04 in HDD1 But can do it without problems in HDD2.(I have 1 SSD, 2 HDD, both HDD are same.)
2. In SSD, I've installed Win10. IF I try to install
Ubuntu18.04 in HDD1, System will ignore it and treat it as a part of win10. And the Boot EFI partition I divide for it will appear in Win10 file explorer.(as pic.1 & 2 shown.)
PC:
MB: Asus Prime Z390-A (BIOS Version: 1302)
Storage: 1. 500G SSD (WDC WDS500G2BOc_00PxH0)
2. 1T (SATA) HDD (WDC WD10EZEX_08WN4A)
3. as same as 2
OS: Win10 1909, Linux Ubuntu18.04
