But after a few seconds it frozen again with a black screen, and after 10 minutes it resumed the boot procedure (Grub screen). Actually, I waited for around 10 minutes, and magically the laptop resumed itself. However I do not power off the laptop because I did fear to brick it again. I want to remark something strange: on two of these laptops, after installing and do a power off cycle, both laptops frozen at BIOS screen ( and message visible, but irresponsive to keyboard). The procedure I followed was shrink Windows, disable UEFI in BIOS, and boot from a ISO CD with Ubuntu (not a USB), with an ethernet conection. Now the good news: I have just installed ubuntu- 12.04.1- desktop- i386 in five of these laptops without problem. I only know they installed Ubuntu from a USB stick. I don't know exactly what Bios configuration neither what Ubuntu version each student tried. I sent them back to Samsung that repaired them promptly by warranty service. Our students bricked four of them when installing Ubuntu. > I hope you are able to get the machine recovered through the vendor.Īt my university, we bought several Samsung Series 5 laptops (NP530U3C model). So, I immediately blamed it, ignored the error messages, recycled power, and started my quest for another USB stick. I was using a really really really old 1GB USB stick that I had dug up from a forgotten corner of a couch. The messages complained about something going wrong with the CPU (sorry, I should have written these down but that is all I remember). These were not kernel oops messages as far as I remember. However, I returned to a black screen containing several error messages. At this point I went away to do something else hoping to return to the installation screen in a couple of minutes. ![]() I figured that it will do its thing and take me through the installation process next. I usually press space bar at this stage and select the option for installing Ubuntu on the system instead of using it as a "live cd". Also, the message consisted of only about four of five words.Īfter this I saw the familiar Ubuntu bootup screen with the image of a keyboard and a person/stick-figure at the bottom of the screen. The message was only displayed for a fraction of second so the only words that I remember were "UEFI" and "secure". During the initial stages of the boot process the screen blinked and I saw a UEFI-related message on the top-left corner of the screen. The machine booted up from the USB stick. > When you tried to boot the image, what happened? At what point did the machine become unresponsive? I used Startup Disk Creator from another machine that was running Ubuntu 12.04.1 (64-bit). > Can you tell us how you prepared the USB stick for booting? This allowed me to boot from the USB stick. I remember that it was on an unexpected place in the BIOS (AFAIK). Eventually, I found an option that said something to the effect that enabling it will allow both legacy and UEFI boot. I tried changing several obvious things in the BIOS such as the boot device order. I tried booting the computer using the 12.10 (64-bit) USB stick but it would not recognize it as a bootable device. > Can you confirm that you had specifically configured your BIOS to boot in UEFI mode? But I will try to answer your questions the best I can: Hopefully one these will work.I did not expect this to happen in my wildest imagination and, hence, did not pay too much attention to the exact steps I followed. Ok.I am off to try a few things.thanks everyone. I did use windows to get into the uefi one time during this process but it looked the same as hitting the F2 key, except when through windows I did not have a pointer. I don't recall seeing it but I was not looking for it either. I was probably refurbishing one when I signed up a few years go and so it was stuck in my I will go into windows settings again and look for boot to usb. I have several old tube ham radios, Swan 350's, 500's. I say that because the USB has a light that comes on, if that is any kind of indicator. I tried the F12 and moving the usb to different ports but it seems like the USB's are not active until after windows starts. Oh, I used Mint 19.2 not through windows. Seems like they simply loaded the iso image direct but in this case.yeah I followed the Mint manual. I dont recall having to do that when I installed 19 on my other computers. I see where passwords are set up but they all appear eyed I used the procedure per Mint installation manual. I will read through that thread in more If there is a password somewhere I am not finding it. I don't know enough about UEFI to know if that is true or not. I found another similar thread on that forum where one guy was saying that some of the UEFI's wont allow another OS system to be installed. Appreciate the had not found that that thread yet. ![]()
