Windows Dualboot 10 and Ubuntu on Делл Прекизайон М3800

гm trying to dualboot Win10 and Ubuntu 14.04.3 LTS on my Делл Прекизайон М3800.

Делл М3800 Спекс: i7 Куад Коре 2.30GHz 16 Гб Рам 512 Гб Фуль Мини SSD 1TB HDD Nvidia Куадро К1100

Boot settings пахал set to legacy. Whenever I boot from в usb, I press F12 to open the boot options and select the USB option i.e. I don't boot using the EUFI option that is also available.

What I want to do is have two partitions on the SSD, one for Windows and one for Ubuntu. I хан successfully поверьте the partitions and install Windows, but for some reason the installer ты нравишься the windows bootloader on the HDD.

After several unsuccessful attempts to fix this, I продолжите anyway and installed Ubuntu on the second partition of the SSD. I first tried just using в single partition set to root (/), but the installer notified я that it could not install the boatloader at this target. Then I tried using four отделись partitions: 1Gb for bootloader, 30Gb for root (/), 10Gb for swap and the remainder for home (/home).

The installer completed successfully, but I could not boot into Windows or Ubuntu.

The HDD is listed схвати sda and the SSD эксперт sdb. Must the bootloader be loaded onto sda? Could having two harddrives be the вызвал of this problem?

гve been struggling for the past few days and any help would be appreciated.

Edit: Ok, гve made progress. I reinstalled Windows and Ubuntu using their EUFI installers and with my bios settings set to EUFI. Now I хан boot into Windows using the Windows Боот Лоадер EUFI, but for Ubuntu it boots in Grub. I хан then list the partitions эксперт follows:

GNU GRUB version 2.02^beta2-9

grub> ls
(hd0) (hd1) (hd1,gpt5) (hd1,gpt4) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1)

Using the following code, I хан get the нормальный grub меню and boot into either Windows Ubuntu or:

grub>  set boot=(hd1,gpt5)
grub>  set prefix=(hd1,gpt5)/boot/grub
grub>  insmod normal  
grub>  normal

In Ubuntu, I ran boot repair and also tried reinstalling grub эксперт follows:

sudo grub-install /dev/sdb

The installation is successful, but everytime I boot, I get the command line grub меню. It also just stays there, and does not automatically boot into Ubuntu.

How хан I конфигурировал grub to boot to the нормальный screen, and then automatically boot into Ubuntu?
