I am trying to dual boot Ubuntu 18.04 from USB stick on HP Win10 i5-8250U with 8gb Ram and 1 TB hard disk. It has 800gb of free space but I am getting several problems stated below:

1] Not getting an option of whether to dual boot or delete win 10 and install ubuntu.

2] Not able to use free space of hard disk.

3] Ubuntu not recognizing pre-installed Win10.

4] Getting fix value of disk space around 7000MB (See image)DISK space limit

Tried many things, watched many things but not getting any solution!

Installation screen is different too

Not much option under device boot

    Click on Device for boot loader Installation drop down menu and check if any other storage device is listed. – Kulfy Nov 20 '18 at 16:34

  • Check BIOS setting if SATA is set to RAID change it to AHCI – Alvin Liang Nov 21 '18 at 3:40
