How to put linux next to windows 10?

Question

linux

Installed win 10 in uefi mode.
I install Linux Ubuntu 14 from a flash drive. From the same flash drive on the laptop was put without problems.
there are options in bios:
OS type:
- Other OS
- Windows 8
Boot Mode Selection:
- UEFI and Legacy
- Legacy Only
- UEFI Only
LAN PXE Boot Option ROM:
- Disabled
- Enabled
Storage Boot Option Control:
- Disabled
- UEFI Only
- Legacy Only
- Legacy First
- UEFI First
Other PCI Device ROM Priority
- UEFI OpROM
- Legacy OpROM
OnChip SATA Type:
- Native IDE
- RAID
- AHCI
here if you select Native - then there is nothing
And if you select RAID or AHCI
The option below appears:
OnChip SATA Port4 / 5 Type: (I have a hard drive connected to port 5)
- IDE
- As SATA Type
Another flash drive mode:
- Auto
- Floppy
- Forced FDD
- Hard Disk
- CD-ROM
I have tried in my opinion almost all possible combinations of these parameters. Most Common Error:
On boot: unable to find a madium containing a live file system
Sometimes I was able to run the install but didn't specify a partition for EFI and ended up with the error "Unable to create partition."
When booting UEFI - the installation is loaded ... but the mouse does not work.
In any download scenario, LAN Internet and wi-fi do not work. Wi-Fi network sees, but can not connect. He thinks and thinks, but to no avail. With LAN in general neponyatki - DHCP and nothing more. But it still doesn't connect. It seems like he writes that he is connected, but there is no Internet. But I have already spat on the Internet, I would put it like that.

Answer 1

According to the idea, it is enough to boot from a USB flash drive, where your ubuntu is in UEFI mode. When installing Ubuntu, manually partition the disks, create a fat32 partition, with the boot mount point. In Ubuntu, everything seems to be able to do everything automatically, there, if I'm not mistaken, you can specify the EFI partition. Specify this section for the bootloader.
If the mother is smart, he will see a new UEFI device from which he can boot, where our bootloader lies.
ps I would generally install the bootloader manually, separately.

Answer 2

Previously, I simply put Linux (Ubuntu) on a separate logical partition, after which GRUB "picked up" Windows and loaded it free when choosing an OS. And when I wanted to demolish Ubuntu, I simply restored the bootloader through Windows.
There were no special problems, except for trifles with free video drivers.
