new ASUS laptop... UEFI & Secure Boot... [RETURNED]
« on: January 21, 2016, 10:11:46 am »
whilst dropping off the ink cartridges for recycling, i noticed a large swath of returned laptops, returned christmas presents I suppose...

Anyway, one I've been eyeing and salivating over for quite a while was amongst them, so I lept. Now just have to to figure out how to get past the secure bootprocess on this Asus Republic of Gamers ~ G751Jl  http://www.asus.com/Notebooks/ROG-G751JL/specifications/

Already have supergrup2 loaded onto a USB... but am now scouring in windows forums for help bypassing... unless someone's got a great tutorial to pass along...  ::)
Ah I see a thread here to read for a wee bit..http://forum.peppermintos.com/index.php/topic,2820.msg27864.html#msg27864

Hi spence,

Don't forget that the newest download of Peppermint Six 64-bit (and only the 64-bit version) has been created explicitly to solve your problem. As I understand it, you don't need to do anything (beyond downloading and installing this newest release in the 64-bit version).

Thus far the bios on the ASUS is NOT allowing me to use a USB to boot, I've downloaded a fresh cpy of p6 iso and used the USB Image Writer in the tools menu.   I've turned off/disabled secure boot in the bios, and each time I reboot I re-set the boot order for USB to be first.

I thought I'd had an epiphany whenIi realized the supergrub USB I was trying to use might not be compatible with the UEFI, so I reformatted it to fat32 and did the P6 live USB rewrite.... but well... poof its back to a really surprisingly slow install of Windows10 with each reboot   
:-\

as an aside... why do search engines seem to turn up "relevant results" from 2005 and 2009 so frequently?

Hi spence

in windows 10 when you go to reboot hold down the shift key...  that wil take you to a special menu where you can tell the pc to boot into the bios...    search around and then tell the bios to change the order of the disks.    The usb dick oops - hahaha   my bad   disk must be insterted when the bios boots so it knows its there.    when you have then made the usb the 1st disk to look at you will be good to go.

Each bios is different so I cant tell you where to find it   but your usb must be inserted in the machine before going into the bios.

Hope this helps   its how I got my lenovo to accept and install p6 with everything on    I did not have to disable anything

Hi spence,

According to the user's manual for your laptop, you should be able to access the BIOS by pressing the F2 (or f2) key immediately after turning the power on (I would suggest pressing the key several times, rapidly). Then, if you get to the BIOS screen(s) go to the one labelled Security to make sure that the access to your USB ports is UNLOCKED. In the screen labelled Boot you can then set the USB port to be at the top of the boot order (I also agree with the suggestion from zebedeeboss: you should have inserted the USB stick with Peppermint Six before turning the computer on).

Regards,

USB has been inserted before each attempt to reboot, but its a good reminder nonetheless... persistence is key...

On the off chance this particular USB was failing... I scrounged around for another one... formated to NTFS this time and created a SuperGrub2 live usb... found the option in Win10 to allow booting with a USB buried in recovery... but also hit alt+f2 to get into bios as well... VOILA...

except the options in supergrub 2 are very unfamiliar, eventually discovered that it could see the cd drive and i inserted my old gparted live cd, but that seems to be frozen as it throws up lots of udevd[random numbers]: timeout: killing.....

so i guess i'll try to eject and  continue putzing around some more...

yikes...
Code: [Select]
/dev/sdb contains GPT signatures, indicating that it has a GPT table.  However, it does not have a valid fake msdos partition table, as it should.  Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables.  Or perhaps you deleted the GPT table, and are now using an msdos partition table.  Is this a GPT partition table?

after acknowledging that yes this laptop has a GPT... i got this:
Code: [Select]
 The backup GPT table is not at the end of the disk, as it should be.  This might mean that another operating system believes the disk is smaller.  Fix, by moving the backup to the end (and removing the old backup)?


Fortunately the very first search result gave me the info i need to confidently just click "FIX" [color]

now time to break for food things...

Ah well... I had searched and found a blow by blow account to dual boot Win8.1 and Ubuntu... and it all seemed to follow along with what I'd discovered in the last 24 hours... so i confidently continued apace...

http://www.dedoimedo.com/computers/dual-boot-windows-8-ubuntu.html

I went ahead and shrunk the Win10 partition, installed a  root and home in ext4 and installed... reboot proceeded to take me right back to Win10 with no Grub2 menu ... ... ... seems more putzing about is required :-\

If you have a UEFI system (and have installed properly), you'll have to CHOOSE to boot Linux .. on HP's it's the F9 key immediately after turning on the PC to access the UEFI loader.

Once into Peppermint we can change the default UEFI boot order.

G'morning... belatedly... yes this ASUS RoG is a UEFI system... per the tutorial I found yesterday I felt like I'd installed the system properly... twice over... this morning i can easily get into the UEFI/BIOS to make sure the USB is preferred... another tutorial reminded me to hold esc after f10 to save my changes... so for the first time I was able to see GRUB 20 minutes ago... first time I chose to try peppermint.... nothing loaded.... 2nd time i tried to install peppermint... nothing loaded... still staring at a blank screeen as i type this...

on my first reboot of the day, Win10 spent half an hour "preparing Windows" before it would restart... so i fear its deleted my install from yesterday somehow :-\

Switched liveUSBs and now have the Grub version 2.02~beta2 display showing.... not sure what to pick here after asking it to "Detect and show boot methods" its showing me 12 lines of code, hoping thats not 12 options...
 ???

After reading more closely,  realized it was offering two options to start peppermint... chose the first [which i can't recollect off top of my head and got the Scanning for BTRFS filesystems message... ended with :
 
Code: [Select]
22.652127 hid-generic 0003:0B05?17FD:0005: usb_submit_(ctrl) failed: -1

which i'm guessing it was going to launch off the usb, but the current USB only has Grub... let me get back here and try option two
