Booting Arch-ISO from USB-Stick in UEFI mode fails

Hi there,
I'm running an Asrock H77M-ITX UEFI mobo. On this system I've already installed Arch on a Samsung 830 SSD (GPT formatted) - but in BIOS legacy mode because I've written the Arch-ISO image with "dd" to an USB-Stick (and UEFI boot mode wasn't even presented at boot).
Out of curiosity I've re-formatted the stick and copied Arch-ISO following … B_from_ISO.
Now I could start the ISO in UEFI mode, but it failed to start gummiboot with the "No loader found. Configuration files in \loader\entries\*.conf are needed." error message, concerning a problem with gummiboot.
Following some advice on the forum, I did this:
- install refind-efi 0.4.7-2
- copy /usr/lib/refind/refindx64.efi to [USB]/EFI/boot and renaming it to bootx64.efi (i.e. replacing the original bootx64.efi from gummiboot)
- Create a new file in the same directory ([USB]/EFI/boot/) called refind.conf
- Add this to it:
scanfor manual
menuentry Arch {
loader /arch/boot/x86_64/vmlinuz
initrd /arch/boot/x86_64/archiso.img
options "gpt loglevel=7 add_efi_memmap none=UEFI_ARCH_x86_64"
With this I can launch Arch-ISO from the USB-Stick in UEFI mode and I can choose Arch from rEFIND. Then Arch-ISO starts booting but it always stops at the same point with this message:
sd 6:0:0:0: [sdb] No Caching mode page present
sd 6:0:0:0: [sdb] Assuming drive cache: write through
sd 6:0:0:0: [sdb] Attached SCSI removable disk
ERROR: '/dev/disk/by-label/' device did not show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, log out when you are finished
sh: can't access tty: job control turned off
[rootfs /]#
sdb is the USB-Stick from which I start Arch-ISO. Again - I didn't use dd to write the ISO to the stick.
Maybe this is pretty easy to solve, but I have to admit that I'm somewhat stuck

Of course. Read:
The "Main Page" ( ) states:
"You've reached the website for Arch Linux, a lightweight and flexible Linux® distribution that tries to Keep It Simple."
"Keep It Simple". Yeah!
In line with that, the "The Arch Way" page ( ) states:
"The following five core principles comprise what is commonly referred to as the Arch Way, or the Arch Philosophy, perhaps best summarized by the acronym KISS for Keep It Simple, Stupid."
The ArchWiki ( ) links to several other pages, such as these:
The "Forum Etiquette" page ( ) states under "Ineffective Discussion":
"Arch is a Do It Yourself community" and "treat others as you would be treated; respect them and their views". I am very much a "do it yourself" person -- that's why I like The Arch Way. I also go by the Golden Rule stated here.
Now, everyone is a newbie at some time. I and other posters here are obviously newbies with respect to ArchLinux. Even experts were newbies at one time. Newbies, by definition, do not necessarily know what they're doing, or where to find information. Hence, Arch's "Beginners' Guide" and such. Hence, posts on this board from newbies asking for help.
As regards initial installation of ArchLinux, and consistent with the above, the FAQ ( ), under "Q) Arch needs an installer. Maybe a GUI installer", states:
"A) Since installation doesn't occur often (read the rest of this article to know more about what rolling release means), it is not a high priority for developers or users. The Installation Guide and Beginners' Guide have been fully updated to use the command-line method. If you're still interested in using an installer, consider using Archboot."
So the basic installation instructions explicitly state that Archboot is not needed.
The "Installation Guide" ( ) says nothing about either Archboot or Archiso.
The "Beginners Guide" ( ) says nothing about either Archboot or Archiso.
The "Archboot" page ( ) is consistent with the above information, because it states:
"Archboot is a set of scripts to generate bootable media for CD/USB/PXE.
It is designed for installation or rescue operation."
The "Archiso" page ( ) states:
"Archiso is a small set of bash scripts that is capable of building fully functional Arch Linux based live CD and USB images. It is a very generic tool, so it could potentially be used to generate anything from rescue systems, install disks, to special interest live CD/DVD/USB systems, and who knows what else."
So the pages describing both Archboot and Archiso clearly state that these tools are oriented towards already-existing installations -- even though it seems that they might be used, in certain circumstances, for initial installations.
I happen to be very new at playing around with installing Linux distros (although I've used Unix/Linux as a regular user for more than 30 years), and am brand new with respect to ArchLinux. I only began playing with it this past Saturday. So I would expect a bit of useful help as opposed to "RTFM!" I will soon get past the need to RTFM for basic tasks, but I have a way to go.
The fact is that for me and a number of other new ArchLinux users, the installation guides simply do not work. C.f. my post . I've done a lot of googling as well as searching the archives on this board, and others have come up against the same show-stopping installation problems that I have. I and others have posted to several recent threads on this board, trying to get past the problems, so far with no success.
Now, the.ridikulus.rat had written:
"You guys are using Archboot's kernel options for Archiso. Thats the issue in both the cases."
Given that neither of these sets of scripts were used by me or swordfish, this comment is not useful.
Given the above, can you or anyone else tell us what Archiso or Archboot might do to help us with our installation problems? Also, can you tell us how we, as newbies, ought to have found out how these might help?

  • Blue screen when booting from USB drive in UEFI mode (2013.07)

    SOLUTION for me was to update the firmware on my ASRock mb as thatu pdate changed the EFI software (by American Megatrends) version from 2.00 to 2.31. However, other users are still experiencing the blue screen.
    When I try to boot Arch Linux 2013.07 with an USB drive in UEFI mode (for installation), I get a blue screen (which is rather a literal description and not a hint towards the old Windows' one) with the message
    Failed to install override security policy (14): Not found
    I made an USB installation media (product: Intenso Rainbow) by following this advice on the wiki.
    I used the july release of Arch for that. First of, after installing the image to the USB stick I found that I needed to correct the label in the archiso-x86_64.conf file to ARCH_201307 (or was it the label of the usb stick, can't remember right now). (Pretty sure it was the same problem with "Linux Live USB Creator" which I used 3-4 months ago...)
    After doing that, I rebooted and selected the entry
    UEFI Intenso Rainbow
    from this list of entries:
    SATA HDJ ... something (the hard drive where Win 7 64 bit is installed with all programs)
    SATA something (hard drive which only contains data)
    Windows Boot Manager
    USB: Intenso Rainbow
    UEFI: Intenso Rainbow
    It went to a blue screen with a message in white text saying
    Failed to install override security policy (14): Not found
    Below that was an OK button which had a black rectangle over it.
    After I experienced the bluescreen, I tried booting the
    USB Intenso Rainbow
    entry and the boot process then worked fine, I got to that Arch menu where I could choose
    Boot Arch Linux (x86_64)
    Boot Arch Linux (i686)
    Boot existing OS
    Run Memtest...
    and so on...
    But just to make sure, I then did the check for UEFI mode according to this and only saw a folder acpi and ... something else I can't really remember, but it definitely was not efi. Thing is, I needwant to boot into UEFI mode as I have Win 7 already installed in UEFI mode.
    Some info about my motherboard: it's from ASRock and is called H67M. The BIOS is dated to 2011-10-26 and is version 1.7.
    So far, I only found a mention of the problem here at

    Ok then, so this thread has also become about the blank screen problem when booting (in this particular case, Arch 2013.06 since 2013.07 seems to be worse).
    srs5694 wrote:Typically, you adjust kernel boot options using your boot manager or boot loader. In GRUB, you hit the "e" key to open an editor. In rEFInd, you hit F2 or Insert twice. I don't recall offhand what key does the job for gummiboot (which I'm pretty sure the Arch installer uses), but I'm certain it's got the feature.
    You are right. Thanks. I realized I had the gummiboot config right in front of me all the time. It's the file 'archiso-x86_64.conf' in \loader\entries (on Windows).
    An addendum: I think the USB: Intenso Rainbow boot option takes me into a GRUB menu. Hitting 'e' in this "big" and fully designed menu didn't do anything IIRC. Hitting 'Tab' did the trick to get into editing the boot command line.
    Hitting 'e' worked in the gummiboot menu though.
    So I tried booting with the following options (also by combining some of them)
    radeon.modeset=0 (I have a Gigabyte 7870 card in this desktop machien)
    but it did not help.
    To be rather safe than sorry: I should mention that there are two grey-ish bars visible on the top and bottom of the screen after I try to boot the first entry, Arch Linux archiso x86_64 UEFI USB. Always has been with those two older Arch version (2013.05+2013.06). I also found another thread where one user talks about using the VGA port of the monitor, which I am currently not, I am using the DVI one, so that's worth a try too. EDIT It did not help either. What I did was setting the primary graphics adapter in the UEFI north bridge configuration menu to 'onboard' which worked immediately when rebooting (I hit the button labeled "Source" on my monitor and it showed it is using the "Analog" mode), but the problem just stayed the same. Adding aforementioned boot options or a combination thereof did not change anything.
    Thanks for the e-mail addresses, I sent one to James Bottomley.

  • [SOLVED] Attempting to boot from USB key in UEFI mode

    I am attempting to boot from a USB Key in UEFI mode to dual boot windows 8 and arch linux.  I'm unsuccessful in getting the USB key to boot in UEFI mode. 
    I am following the guide on page: … _Interface due to the fact that I am receiving error " No loader found. Configuration files in /loader/entries/*.conf are needed."
    I am attempting to use the archiso media and have created refind.conf according to in (USB)/EFI/boot/refind.conf
    However, I'm stuck on the initial step from the wiki: Install refind-efi pkg. In the usb's filesystem, overwrite the file EFI/boot/bootx64.efi with /usr/lib/refind/refind_x64.efi.
    My question is: How do I install the refind-efi package onto the USB key using an arch linux host machine and the USB plugged into the machine.

    swordfish wrote:1. Might be possible, that the uefi integration is pretty bad. Have you already looked for an update of the uefi bios?
    This is my thought, too. The "memory map has changed" message sounds like the firmware is messing with the way memory is laid out in the middle of the boot process. A firmware update, if available, is likely to be the best way to deal with this problem. If not, trying Fedora's patched GRUB Legacy and GRUB 2 are also worth doing; it's conceivable that one of them includes a workaround for the problem.
    2. In your first posting you mention Windows 8 on this machine. Is W8 starting in uefi mode?
    This is important, but if the disk uses GPT partitioning, then Windows is starting in EFI mode.
    3. If W8 is starting in uefi mode, are you sure that secure boot is disabled?
    It is; if it weren't, neither rEFInd nor ELILO could start -- or even if they were configured to start in Secure Boot mode, ELILO doesn't launch its kernels in a way that respects Secure Boot, so the ELILO failure can't be caused by Secure Boot. Also, when launched with Secure Boot active, rEFInd returns a clear error message about a security violation and then returns to its main menu; it doesn't hang the computer.
    One possible workaround occurs to me if all else fails: Have rEFInd launch a BIOS version of GRUB. The setup procedure, in outline, is as follows:
    Create a BIOS Boot Partition on the disk.
    Install the BIOS version of GRUB 2.
    Configure rEFInd to include a scan for BIOS-mode boot loaders by uncommenting the "scanfor" line in refind.conf and adding "hdbios" to it.
    Thereafter, you'll see a new "generic" icon, which should launch GRUB, which should launch Linux in BIOS mode, even though Windows launches in EFI mode. This will work on most modern UEFI-based computers with a single hard disk, but things get trickier with multiple disks and with some UEFI implementations that lack the necessary firmware features. If a future firmware update fixes the problem, or if a future kernel's EFI stub loader includes a workaround, the EFI-mode booting will become an option once again.

  • Boot ISO from USB-stick!

    I have found a very nice utility that allows you to put an ISO on an USB-stick and boot from it like it's a real CD/DVD player:

    This program is great and actually just saved a brand spankin new MSI GX660 from certain death,  I had it packed and ready to ship back to newegg hours after I got it because recovery would not work.  But a fresh win 7 iso image and a 4gig flash drive and unetbootin saved my laptop and weeks of certain stress.
    All I wanted was my GX660 to run out of the box and unetbootin assisted in the processs immensely!

  • Re: Satellite NB10T-A-101 - cannot boot from USB stick

    I bought a new Toshiba Satellite NB10T-A-101 and would like to boost performance by changing the HDD by a SSD and install windows 8.1 Pro.
    I'm however unable to boot from USB, it always mention:
    +Reboot and select proper Boot Device or insert boot media in selected boot device and press a key.+
    I already disabled secure boot, used 5+ different usb sticks (work all fine on other laptops).
    Can you please tell me what the approach is to change the HDD and then boot from a bootable (UEFI) usb stick.
    Thank you.

    The notebook Satellite NB10T-A-101 was equipped with an Intel N2810 CPU which is part of the new Intel Bay Trail-M platform.
    This new Intel Bay Trail technology allows the installation of UEFI capable systems:
    Win 8 or Win 8.1
    Just few questions:
    Did you already change the HDD to SSD drive?
    If yes, is the new SSD drive recognized in the BIOS?
    Did you try to boot from this Win 8.1 USB flash memory stick before you switched to SSD drive?

    Can all macbooks boot from usb(stick,hdd) and firewire(hdd) an os: linux, win, mac os x, opensolaris, etc?
    what about:

    Disconnect everything hooked up to the PC except the keyboard, mouse and monitor.
    Then use this method to flash the BIOS.  It is the safest way to go.
    USB Device BIOS Flashing in DOS
    DOS Flash  (DOSFlash.exe, FlshUefi.cpu) is the DOS-compatible System BIOS flash utility that can be used from a DOS bootable storage device (where "DOS" refers to any of a number of compatible operating systems such as FreeDOS, MS-DOS or DR-DOS). FlshUefi.cpu is the required driver for DOSFlash.exe. To flash the System BIOS from a bootable USB storage device, you will need to copy the contents of the DOS Flash folder to the USB device, boot the PC from the USB device, and execute the DOSFlash application. To see a more complete description of the DOS flash utilities, view DOSFlash.txt located in the DOS Flash folder. This folder also contains the required binary image of the BIOS.  The binary image file is named xxx_MMmm.bin where "xxx" is the BIOS family, "MM" is the major version number, and "mm" is the minor version number.  This file can be copied to the root directory of any USB removable medium for use with the F10 setup "Flash System ROM" option 
    View Contents of DOS Flash Folder
    The links on this post don't work. I copied the section from the BIOS flashing instructions for the specific section you need.

    Hmm, when you mean "bootable" are you meaning booting a operating system from the USB to run the computer with?
    Because that's what "booting" means, not mounting, which is what I think you mean.
    I say this is because you mentioned a PC, and a generic PC can't normally boot from a USB with OS X installed without a LOT of extra help of the hacking/breaking software agreement kind which is beyond the capability of most.
    If you mean your USB thumb drive is not mounting or showing up on the computer to trade files, then please tell us how you formatted the USB or if you didn't or not and it's volume size.
    Also if it does have OS X on it, what version and where did you install it from, because it might be lacking the hardware drivers for the other Mac.

  • Portege P3500: It's possible to start from USB-stick?

    Is it possible to start from usb-stick? i have tried to make a bootable usb-stick , and it really worked on my pc at home , but not on the laptop ..bios settings are ok , as far i know (usb-fdd legacy enable , first boot device fdd)
    where is the problem ?

    Try to update bios. Even though it has that option does not mean that it will. Make sure in BIOS that legacy emulation is enabled as well. Then connect your USB and turn on the computer. Go into bios and check to see if your USB keystick is located under boot devices, which it should be. Other then that, you might have installed the boot program wrong. CD's etc have a boot.ini file. Basically an ini means initiate. So boot.ini initiates boot process. If this is configured wrong, or doesnt exist on the boot device you are using, it will not boot from the device even if configured in BIOS.

  • After BIOS Update cannot boot Satellite C640 using USB Stick

    After upgrading my Toshiba Satellite C640-10E (PSC02E) bios to 2.00 WIN, I cannot boot the laptop using USB Stick, When I checked the BIOS using F2 I was stunned because the USB connected to laptop was labeled as FLOPPY drive. Is there any option to downgrade the BIOS?

    From my experience the BIOS is able to boot from
    - USB FDD (floppy disk)
    - Primary HDD,
    - USB Memory stick
    - Network (LAN)
    So I dont think that your USB memory is recognized as a USB FDD but the USB FDD appears as a separate boot device.
    It would be interesting to know if another USB flash memory would act as your old USB flash stick.
    PS: as Tonny suggested: you cannot downgrade because you dont have previous BIOS version only Toshiba service agents are able to downgrade the BIOS using traditional BIOS.

    What I've found:
    - I cannot run any Jar file I try if it is on a USB stick and I double-click on the jar file in my Mac
    - I CAN run jar files from a CD by double-clicking
    - I CAN run jar files from USB sticks on Windows directly from the window
    - I CAN run jar files from a USB stick on a mac if I call "java -jar" directly from the terminal
    I have tried running from USB sticks on several different Macs, and I've tried a number of different Jars that I've created over the years -- nothing works. The Java code isn't doing any path-based finding of files or anything like that.
    Anyone else tried this? Are there any solutions?

    Try this:
    With the stick plugged in, go to Finder->Applications->Utilities->Disk Utility.  From there, you should see your memory stick appear in a sidebar on the left.  Click on it, then click on the "erase" tab and follow the instructions.
