Sorry for my bad English: I'm totally new at Ubuntu, and i'm trying to install it in dual boot with W10 in my laptop (hp omen 15, i7 7700hq, 12gbram, gtx1050, hdd 1tb, ssd crucial 275gb m.2, the usb I'm using is a 32gb kingston 3.0).
I've tried 11 times (literally) installing ubuntu, and it always crashes when I hit the reboot now button, it freezes for about 3 minutes in the reboot now screen, and after that gives an error in a black screen. It never has boot on Ubuntu after that. Got to say that almost all time I've tried with the laptop disconnected from any powersource and with the external peripherals also disconnected, as I've read that sometimes it gets stuck if you have two monitors and similar things.
On early tries it used to give microcode errors (0x52 if I remember well), but now (it's supposed that I've updated the microcodes) it gives other ones. (I'll put photos later). Almost always it finished with two messages Syncronizing SCSI cache, this one for the sda and sdb devices.
When I try to install it on the SSD I'm using a partition of 50gb ext4 on / and another swap of 5gbs, and when I try that on the HDD I've used two partitions apart from the swap of 5gbs, one called root and other one called home, the first one on / and the second on /home, each one of 50gbs.
What I've tried:
- Update microcode and BIOS (F50 now, before was at F34).
- Install it via different USB devices, and in ISO and DD modes (those which Rufus gives, and yes, always in GPT, my bios is in uefi mode).
- Install it on the SSD and on the HDD, as sometimes the error after pressing the
reboot buttonwas[sdc]No caching mode was found. SDA is the SSD, SDB the HDD and SDC the USB, but idk, I wanted to try. - Install 18.04LTS and 18.10, but neither worked.
- Install it directly when it boots on my usb via
install nowand also viatry ubuntu. - Install it having the secure boot activated, now it's deactivated.
- I've also tried taking of the usb after pressing reboot, as sometimes it said that no cache page was found at sdc, it repeated the error despite not being inserted on the usb port.
I don't know which is the problem and how to solve it... Thanks in advance.
FINALLY, I managed to install Lubuntu 18.10 (I gave up with Ubuntu) but I don't manage my laptop to detect the external monitor (via HDMI), I´ve googled and anything, since directly it doesn't detect it (now I´m writing on it on W10 so it works properly and I´ve tried rebooting Lubuntu with no success). Does anyone have any idea of what could I do? Thanks in advande.
(I don´t know if I should make this question on another different post, if yes, let me know :) ).
Boot and repeatedly hit the

Now make the same change in the file as you did to boot. Save & exit, then run
Let us know if this fixes your machine.
If you installed it in dual boot after restart it'll obviously boot in Windows even if you correctly installed Ubuntu.
At the installation Ubuntu 18.04 should recognize there is also another OS on the disk, and it should prompt you if you want to install them in parallel in order for GRUB to handle both OS entries.
If you didn't you'll have to manually launch the partition containing Ubuntu from BIOS. You can do it in the same way you boot from USB, by moving up the partition containing Ubuntu in the BOOT order.
