Flex 2 Windows 8.1 re-install from USB boot device ignored

Sorry to jum into your thread, but i've been trying to re-install Windows 8.1 on my Flex 2 but cannot succeed in booting from USB drive with the Windows 8.1 installation.
Same Thumb drive work on other laptop, but on this one, the Flex just ignore it and continue to load Windows 8.1 from it's internal HDD.
I tried to shutdown the Flex and turn it on using the NUVO button, i selected the USB as boot device and still got boot from internal HDD.
would appreciate any help from your side.
Moderator edit: Matched subject to content

Right, just checked the GNU documentation and you should use this format to boot Windows on sda1:
menuentry "Windows" {
insmod chain
insmod ntfs
set root=(hd0,1)
chainloader +1
https://www.gnu.org/software/grub/manua … ading.html
However:
If you have installed DOS (or Windows) on a non-first hard disk, you have to use the disk swapping technique, because that OS cannot boot from any disks but the first one. The workaround used in GRUB is the command drivemap
Another problem arises if you installed more than one set of DOS/Windows onto one disk, because they could be confused if there are more than one primary partitions for DOS/Windows. Certainly you should avoid doing this, but there is a solution if you do want to do so. Use the partition hiding/unhiding technique.

Mid 2010 iMac upgraded SSD, can't seem to install windows via bootcamp. Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems error

I have windows 8.1 on DVD & on USB CF Reader/Card. I've followed the full steps in bootcamp, but when it restarts and its time to select the bootcamp partition to install windows (after alt rebooting to the efi startup) I get the "Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems" error.
I've scoured the internet trying different solutions that seem to work for everyone else, but to no avail. I've reformatted from that screen, doesn't help. I've removed bootcamp partition and manually partitioned using disk util, leaving it empty once partition-wise, and filling it with a blank partition the second time. I've done a full back up and clean re-install of Yosemite, and nothing seems to be working.
Thats when I switched to DVD install, as I heard sometimes you can't install with a CF card. When I alt-boot, I can see EFI-windows and windows, but if I select EFI-windows, same problem as before, and if I select windows, I get the black screen of "no bootable device please insert boot disk and press any key."
I've been stuck w/o bootcamp for over 2 years now. Anyone, please help?
Mid 2010 iMac running 256gb SSD, Yosemite 10.10.1 trying to install windows 8.1

I am having the same problem. Windows is trying to install. It identifies the various partitions but says that I cannot install Windows on the Boot Camp partition or any other. I select Drive options (advanced) and Format the Boot Camp drive, but it makes no difference.
This is the Windows error:
Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.
Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer BIOS menu.
I am not sure what Csound1 is suggesting with that post above. There are some involved suggestions over here <https://discussions.apple.com/message/23548999#23548999> about using Disk Utility to delete the Boot Camp partition and create new ones - is that the idea?

[SOLVED] external USB HDD fails to install arch w/boot device ERROR

I've been working on installing arch linux via an external USB harddrive (specifically seagate free agent go 320GB) for 1 week now, and everytime I failed - until TODAY! thankfully I found this post, where user Dieter@be references this link, which displays BUG ID#17231 at the top titled "Can't boot LiveCDs 2009.08 (/dev/archiso doesn't show up)". the bug report states ::
I can't boot the LiveCDs 2009.08, neither netinstall nor core.
When it tries to access /dev/archiso it shows these messages:
:: Waiting for boot device ...
Waiting 30 seconds for device /dev/archiso ...
ERROR: boot device didn't show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, logout when you are finished
ramfs$
reading further thru this bug report, I found a very insightful post by Heiko Baums (cyberpatrol) where he says the following, and I quote ::
Problem found. The link /dev/archiso wasn't created.
After
ramfs$ cd /dev
ramfs$ ln -s sr0 archiso
ramfs$ exit
it continued booting correctly.
And sg was also loaded after this. ;-)
as you see, the bug report was for the CD version, not the USB version - yet, my issue with the USB bootdisk was the same, (no matter which boot disk I tried = netinstall, core, .img, .iso, etc) meaning I got the EXACT same error = "ERROR: boot device didn't show up after 30 seconds ..." ! well, I figured that I'd try one of the new fancy ISOs found @ http://build.archlinux.org/isos/ - specifically I use/used archlinux-2010.03.04-netinstall-x86_64.iso.
upon running Unetbootin from windows 7, and choose to install the ISO archlinux-2010.03.04-netinstall-x86_64.iso to my first partition on my USB harddrive (that first partition being FAT32, and had already been set as bootable previously), that completed successfully. I rebooted, and choose to boot from USB drive, the ISOlinux bootloader came up as normal, I choose DEFAULT and off it went.... sure enough, it errored out at the same place as listed in the bug report ::
:: Waiting for boot device ...
Waiting 30 seconds for device /dev/archiso ...
ERROR: boot device didn't show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, logout when you are finished
ramfs$
this time though, I issued the following 2 commands ::
ln -s /dev/sdb1 /dev/archiso
exit
from there, EVERYTHING worked as it should!
to recap: the solution for me was create a symbolic link pointing /dev/archiso => to my partition which held the archlinux netinstall (which is where I told Unetbootin to install it to)! done and done. I felt this needed to be posted here, as I could not find this solution after MANY google searches, archlinux wiki searches, forum searches, etc. honestly, I think it would be prudent to have this tidbit of information added to the Install from USB stick archwiki page as a side note to those that may run into this issue.
this is not the FIRST time I have run into this problem with a USB install of archlinux, but this is the FIRST time I found a fix! thanks to all the great posts I reference here, without this information I dont think I would have been able to install archlinux on my new alienware m11x laptop.
-peace-
PS: no amount of rootdelay=XX nor pmedia=usb nor usbdelay=XX would work in my above attempts either.

FAT16 here. Parted Magic sees my USB drive as sdd. I tried your way and surprise, surprise, it didn't work.
ln -sf /dev/sdd /dev/archiso
mount -t vfat /dev/archiso /bootmnt
mount : Invalid argument
I thought maybe you meant mount -f vfat /dev/archiso /bootmnt instead. I tried it too, it resulted in a kernel panic.
What else can I try besides installing from a IDE/SATA CD drive ? Because this issue is NOT solved. At least not for me. Wonder if "archlinux-2010.04.05-netinstall-i686.iso" from the here will solve it (really hope so).

Enable Bootcamp to install from usb for OSX 10.9**WORKS**

So basically, I have trying to install windows on my mbp using a usb drive. However bootcamp wont allow me to do so since I have a optical drive on the laptop. I have been searching for a long time and eventually came across this solution and I would like to share this so u guys dont have to google all over the place again .
The solutions given before by changing info.plist is correct except that now Bootcamp crashes everytime you change it in OSX 10.9.
Full solution:
1. Add your Boot Rom Version(from system info) under DARequiredROMVersions.
2. Add Model Identifier(from system info) under PreUSBBootSupportedModels
3. Delete "Pre" from "PreUSBBootSupportedModels", so you have "USBBootSupportedModels"
The first 3 steps are same as before and if its not clear you can easily google solutions with screenshots.
The next step is only for OSX 10.9, as it employs some kind of code signature to prevent you from changing info.plist and cause bootcamp to crash.
4. Open your terminal, use the following command
sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app
Sudo means using administrator privilege and u need to enter your mac password. And the command resigns the bootcamp application so that it runs with the new info.plist file and not crash.
5. Continue on with your installation....
Cheers.
P.S. back up info.plist before u change anything.

do you have multiple partitions on your USB stick? And what partition table does it use?
I have two windows installers. One is on a 4GB single partition fat32 formatted stick, and one is on a 5GB partitions of a 500GB USB HDD. On the USB HDD I have windows as second partition. First is OSX installer. I noticed that I can boot in BIOS mode with the 4GB USB stick, but not with the 500GB USB HDD.
So try a windows formatted USB stick with a single partition. See if that works.
Be carefull with google.. In the last few days I have been researching some bootcamp related things and there is waaaay more wrong information of people that tell others what they 'heard' than that there is right information of those who know how stuff works.
I am of the 2nd category btw. I only tell you what I know for sure. If an '06 macbook with ODD can boot of of USB into BIOS mode, then so should you.
Edit: The reason the Windows EFI installers says it found an MBR partition only is because by default the disk is in GPT mode with a 'protected' mbr so that non-gpt aware programs wont look and scream "free space! ".
In order for Bootcamp to install in legacy BIOS mode it converts this 'protective' MBR into a "hybrid" MBR. If you download the open source app "Gdisk", install it, and type "sudo gdisk /dev/disk0" in terminal you will see there is either a protective or hybrid MBR on the disk.
Formatting a disk to fat32 with any OSX tool (BC Utility or disk utility) will convert the protective MBR to Hybrid MBR.
Gdisk allows you to reset this to a protective MBR as described here: http://superuser.com/questions/508026/windows-detects-gpt-disk-as-mbr-in-efi-boo t
Hybrid MBR: Full Bootcamp compatibility. OSX knows whats up and decides everything. Windows installs in legacy BIOS mode on an MBR type disk.
Protective MBR: Bootcamp utility and OSX are not used since they would convert the disk to a hybrid MBR. This mode is compatible with booting in EFI mode. EFI compatible Windows versions (7 partially, 8 completely) will live alongside OS X, for the most without problems. And will install on a GPT type disk.
Hope to have helped you with this. Took me three full days of non-stop reading to figure this out.

Edit 2: Make damned sure you have a backup of your system. Messing around with partition types and tables shouldnt hurt when you know what you're doing. But since I know this for three days, and you apparently havent found this yet, I think it's safe to say both of us aren't yet 100% sure of what we're doing .

Trying to do clean install from USB after kernel problem

MacBook Pro 13" Mid 2010
- was running OS X v 10.9
- 2.4 GHz Intel Core 2 Duo processor
Machine was running extremely slow, unable to do anything with it. When booted to safe mode, lag issue was not present. Booted to Disk Utility, left column showed (photoshoped to show how it looked originally):
Verified and repaired Macintosh HD and disk1 - OS X Base System, no problems.
Booted Option R - Erased Macintosh HD, tried to do new install from online, failed 3 times (took in excess of 8 hours each time). Still lagging, mouse movement very irratic.
Reset SMC, and NVRAM, some improvemet with mouse movement and speed
Read suggestions online to erase entire drive, boot from USB to DU, and install from bootable USB. Tried to do that. When in the boot from screen (Option) mouse lag not apparent. Chose USB, it opened up DU. Erased Macintosh HD again. Cannot delete or unmount OS X Base System, new screen looks like this:
From this screen, I exit back to the first screen and select Install OS X Mavericks, it gives me the choice to install on USB or Macintosh HD, I chose the latter, follow the steps, get a screen saying it's installing then it brings me back to DU after about 10 min. What am I missing here? Do I need to partition Macintosh HD creating a boot portion? I'm not a Mac person, I'm trying to fix this for my son.
Can I even do an install on Macintosh HD? I get that prior to booting to USB, I was using disk1, and so it couldn't be erased, but booting from the USB, would I not be using DU from the USB, and therefore able to clean the HD and start fresh? I'm guessing that the boot disk is causing the lag, and want to get rid of it.
Or is the disk showing disk3: OS X Install ESD accessible someone to do the install and I'm just going in circles?
I'd be extremely appreciative of any help you could provide, thank you.

Try this: (1) On your Mac mount the disk in the Time Capsule (probably called "Data"). (2) In the "Data" volume locate and mount the "sparsebundle" image that contains the "old" backups. (3) Click-and-hold on the Time Machine icon in the Dock, then choose from the pop-up menu the option to "Browse Other Time Machine Disks". That should give you access to the old files.

Install from USB external HD

Hi all,
I'm installing Snow Leopard from a USB hard disk because the CD drive in my machine is dead. The install runs for about 10 minutes then gives me an error that states the CD is dirty. This is impossible because I'm installing from an external disk.
If I try rebooting into the image on the external HD then installing, the same thing happens except the installer complains about being unable to install support files.
Any pointers?

Create a disk image of the DVD. Then restore that image to an external drive. I haven't installed anything directly from CD/DVD for several years now.
yes, I know the method of course. i wanted to see what exactly the OP did since their DVD drive is not working.

Hi Evan,
you cannot install from hardware specific install disks that shipped with another computer. Besides this it would also be illegal. You have to buy the retail full install DVD.

OS X Snow Leopard install from (non-boot) USB memory stick

oi~
just bought this second hand and after i finally got into it (the seller forgot name/password) it turns out the DVD drive is malfunctioning, i was able to watch part of a movie but it will not boot from it nor let me install from DVD. (seller is not calling me back or responding to anything i sent) bottom-line for now i can live without the DVD drive but i would like to install OS X Snow Leopard.. can i copy the DVD contents onto a 8 GB USB memory stick (using a Vista pc) and install from the USB stick ? it does not have to be bootable as i realize to do that you must use the Mac.
i also have a old(er) iMac, maybe i can use that copy copy contents (if it even reads DVD's)
any help appreciated.. thanks.

thanks..
i thought i put my model # in my info, it's a MB061LL/B (Apple MacBook "Core 2 Duo" 2.0 13") darn... i keep getting stuck when i think i have a solution. so copying the contents of the disc to a network pc will not work either. or, could i make the
USB stick bootable and copy contents using a old iMac ?
added: i might be able to borrow a MacBook w/ a working DVD player.. is it a fairly quick and painless process to create a bootable USB stick + put OS X Snow Leopard on it ? (i'm rusty when it comes to Mac..)

My iTunes installation via Windows 7 does not install the Apple Mobile Device Support file

I have followed several suggestions to resolve the problem caused because of my update of iTunes does not install the Apple Mobile Device Support folder, thus making it impossible for me to sync my iPhone 4S to my desktop version of iTunes. I have tried to install the AppleMobileDeviceSupport.msi file and it almost completes the installation before "rolling back" the entire process and giving me a message that there was a problem with the installation. Has anyone been able to solve this problem. I use Windows 7. I have seem some :"solutions" that seem to work for some people, but not for me, and evidently not for many others? Finally, would it matter if I installed Safari on my desktop and tried to install iTunes using Safari?

Let's try a standalone Apple Mobile Device Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of why it's not installing under normal conditions.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleMobileDeviceSupport.msi (or AppleMobileDeviceSupport64.msi) to do a standalone AMDS install.
(If it offers you the choice to remove or repair, choose "Remove", and if the uninstall goes through successfully, see if you can reinstall by doubleclicking the AppleMobileDeviceSupport.msi again.)
Does it install (or uninstall and then reinstall) properly for you? If so, can you get a normal iTunes install to go through properly now?
If instead you get an error message during the install (or uninstall), let us know what it says. (Precise text, please.)

Problems with creating a USB boot device for Windows 8.1

My iMac (late 2012) running OSX Mavericks is encountering problems creating a Windows 8.1 install disk via a USB thumbdrive. The drive has 8gb of space available, which is enough to fit windows. But when I choose my ISO image and select the drive I recieve an error message. The error is 'Bootcamp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation.
I'm certain this ISO definately contains 64-bit, so I'm slightly confused.
I've followed instructions found in other discussions talking about adding an extra line of information to 'info.plist' found inside the Package Contents for bootcamp, but that has also not worked. If I try that, Bootcamp crashes upon being clicked every time.
Any help is appreciated

First up: a question. How did you fix the crashing Bootcamp Utility? It would help out this guy: https://discussions.apple.com/message/23523783?ac_cid=tw123456#23523783
Next up: A possible solution (also posted here:https://discussions.apple.com/message/23523783?ac_cid=tw123456#23523783)
=====================
It's possible you have a Windows ISO for both 32- and 64-bit. In this case it's probably detecting the presence of the 32-bit installer and forgets to look for another 64-bit version.
A way to work around this is to not use the Bootcamp Assistant utility by following the listed steps:
The way installing Windows should work either way using the Legacy BIOS mode:
- Get a Windows ISO or DVD and copy the contents over to a freshly fat32 formatted USB stick of at least 4GB.
- Download the Apple Bootcamp Support Software (4.x or 5.x, 5.x only supports 64-bit, get that if you are going 64-bit);
- Copy the content of the Support Software folder over the the same USB stick from the first step. It should fit just right (it did on my 4GB stick with 2MB te spare!);
- Use disk utility to partition your disk. Make sure the partition for Windows is Fat32 and at least 30GB;
- Reboot your machine while holding Option/Alt at the chime;
- You should be able to select either your OSX HDD or your USB stick labeled "Windows" -> Select Windows and press enter or click the arrow;
- The Windows installer should now load, format the previously made Windows partition to NTFS;
- Continue on your way.
Can you try what I typed above? If it doesn't work, can you let me know at what step things go differently than described?
Edit: This is based on the logical conclusion that any Mac that was shipped without ODD should be able to boot from USB.
Edit2:
One other note is that Mac's have trouble booting from USB when multiple USB storage devices are attached. So make sure you connect only one storage device.
=====================
Best of luck to you!

Windows 8 does not have a USB boot option

QuestionHow can I boot my Windows 8 laptop from a USB device? I created a recovery disk on a USB thumb drive.
So far I have:
Entered into the UEFI (BIOS) and set USB to boot first.
Disabled secure boot.
I tried to reboot using the general setup options for startup in the windows settings page. I choose boot from USB through the UEFI, but got an error message that system does not have a USB boot option.
To confirm I also created a bootable DVD with an ISO burner, but my laptop cannot detect a DVD boot option either.
I assumed that the firmware of the UEFI for this computer allowed a bootable USB but in practice I cannot seem to get this work.
AnswerTo assist with not being able to boot from a USB device on a Windows 8 laptop, perform the following:
Plug in USB bootable device.
Hold down F12 when restarting and access UEFI menu (option is below drive list). If system is set to fast boot, CLICK HERE for instructions on entering the UEFI.
Go to UEFI and make USB "1st boot".
Disable secure boot.
Go to the "Advance" Tab, select "System".
Change boot order from UEFI to CSM.
Save changes and exit (F10).
Computer will restart and boot from USB drive.
When finished go back into the UEFI and set defaults then save changes and exit (F10). Windows 8 will reboot normally next reboot.

Done that, only choices are "Set up Firefox to Sync" & "Pair a Device". No ''UNLINK THIS DEVICE". Your turn.

Windows Server 2012 Group Policy Block USB Storage devices @ User Level Not getting applied on a Domain Client machine with Windows Server 2008 R2. Why?

Hello,
I have a Windows Server 2012 R2.
I have configured the Group Policy on it to block the usage of USB - Storage Devices @ user level on the client machines. It works properly for my Windows 7 client machines but it's not working on one of the machine having Windows Server 2008 R2 installed
on it (this machine is also a domain client in the same domain).
I will really be thankful if anyone can suggest some solution to this issue.
Please feel free to write back in-case I have missed anything obvious to be shared.

Inability to boot from alternative boot devices

Hi… I apologize if this has been covered, but my searching hasn't found anything definitive.
A friend asked me to replace the hard drive in his Macbook, one month out of warranty. The techs at Apple (I understand he went to a Genius Bar) told him that the hard drive is the problem on the machine.
The computer is a Macbook late 2008, and it's not booting. In an attempt to salvage some of the HD's data, I tried booting from an external, but no dice. The problem is, now I'm thinking it might be more than just the hard drive… when my hard drive crapped out on me, I was able to boot from my external, from a boot DVD, etc.
When I first got it, it would start up, go to a white/grey screen, and that's it.
Then I zapped the PRAM, and I started getting chimes, but that's it.
I held down option to get boot options, and was able to see my external hard drive, but never my boot DVD (this is not an OS X DVD, it's an 'emergency disc' with various software). It was also able to see my Macbook's HD, which I connected in Target Disk Mode. However, it was never able to open either drive. The cursor would show up on the screen, followed by the orange little FW HD icon, already selected (the Macbook has one FW port, so I was unable to connect them both at the same time), but that's it. Clicking, hitting enter, etc, did nothing. No discernible reaction.
Just for kicks, I reset the SMC. When I restarted the computer, I now got a flashing folder… which actually bodes well, as that's usually just a HD issue, not logic board (as far as I know). But when I rebooted again to try to boot from another external, etc, I got the white/grey screen again, and that's it.
So, my question is this:
Is there anything else I can try? Either to fix this or to eliminate HD vs. other components.
Is this just a hard drive issue?
If this is something else (e.g. logic board), what would it cost to replace?
One thing I found on Google mentioned that removing the hard drive, if totally dead, could possible fix this. Can this be? I mean, I'm telling the computer to bypass the hard drive entirely!
Thanks in advance… I'm hoping I remembered everything I tried.

Hi hudgie,
There's any number of situations that occur when a HD fails, having worked at one of those "Genius Bars" for a while I can honestly say that there's no across the board, failure indication. Some of the more common indicates were:
1.) Startup to a flashing folder with question mark
2.) Loud clicking/grinding noise
3.) No noise/responsiveness from drive
4.) System bus lockup / inability to launch startup manager / inability to boot from external source
It sounds like you're dealing with situation #4. When my HD failed in my MacBook Pro it did the same thing, the drive would lock up the startup sequence and prevent me from doing anything. When I removed the HD and attempted to boot from an external source it would then startup just fine.
I personally don't think you're dealing with a logic board issue, but the only way to confirm that would be to connect another HD to the drive connection and try to boot the machine. If the issue persists I'd even go so far as to replace the SATA connection cable and then point a finger at the logic board.
Apple offers a "flat rate" repair service for machines out of warranty but with no accidental damage, I believe the price runs about ~$350. If you're just replacing a HD or the SATA cable and drive it's much cheaper to do it yourself. If you determine that the logic board is the point of failure, then I'd go the route of having Apple do it for you. Especially because the repair service grants you a 90-day limited warranty on the machine.

Install Windows to new Hard drive from USB system backup

I have bought a new 1TB hard drive for my G580 and have created a USB system recovery drive using Windows 8.1's system restore functionality but when I swap the drives out and try to reset the PC to factory setting settings it fails by saying a partition can't be found.
