Dualbooting Win10+Ubuntu18.10. Used UUI, Rufus, none of them helped. Is there any possible way to fix that? As I can see there's no answer to this question in the web.
Booting 'Boot ubuntu'
(hd0,0) Filesystem type is iso9660_Joliet, using whole disk
[Linux-bzImage, setup=0x4200, size=0x821b58]
initrd /casper/ILUG
Error 15: (http://grub4dos.chenall.net/e/15) File not found
Press any key to continue...

Not enough information there to help much.
What stage are you at; are you still trying to boot the USB install disk, or have you been through the installation and now trying to boot to the installed OS?
I assume the latter but would like to be sure.
I am also a little unsure about why your system is looking for grub4dos, which to the best of my knowledge is not normally needed in a standard installed system.

Thank god that someone is trying to help me...
No, I didn't even install Ubuntu. I'm still at the USB install disk stage.
I don't know either why it shows grub4dos, it's like: i think i'm the only one having that issue. I formatted the PC and it didn't help aswell. BIOS Boot Order is right, same as last year, when I installed Ubuntu 17.10.
17.04, 17.10, 18.04 - no problems.

Most find this works:
https://help.ubuntu.com/community/mkusb
https://wiki.ubuntu.com/Win32DiskImager/iso2usb
If new UEFI system, you do not really need installer:
If UEFI only, then can just extract ISO with 7-zip to FAT32 formatted drive with boot flag on FAT32 partition.
Will not boot in BIOS mode
UEFI only USB key, just extract ISO ( 7 zip or similar) to FAT32 formatted flash drive partition & set boot flag.

You should aslso check that your .iso file used to create the USB is a good one by checking the hashes as shown at https://help.ubuntu.com/community/UbuntuHashes
If it does not match totally download again, preferably with a torrent client, eg transmission.

What do you mean by "checking the hashes"? Sorry, but I don't understand it.

Any chance you are using EasyBCD?
