Windows 8.1 usb

I have installed Windows 8.1 in my 15" Macbook Pro with Retina late 2013 using EFI (without bootcamp) and also installed the latest BootCamp drivers. However, I have everything work (including the NVidia discrete graphics) but the usb. Every time I plug in my external disk or flash drive, the partition icon shows up and disappears alternatively. This lasts continously untill I unplug the usb drive and I never can explore the usb drive under Windows. I had a macbook air 2011 also and that has the same issue with windows 8.1 (this copy was installed using BootCamp). So I ownder if anyone has met the same issue and how you solve it.

Device Type: Other Devices
Manufacturer: Unknown
Location: on Intel(R) USB3.0 eXtensible Host Controller - 01.00 (Microsoft)
Device Status:
The drivers for this device are not installed (Code 28).
"Update Driver" produces no results.
Hi,
In the Intel download center, we can only find the driver for Windows 7
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3467
And the link below mentioned that Windows 8* has a native in-box USB 3.0 driver.
http://www.intel.com/support/chipsets/usb3/sb/CS-033977.htm
Windows 8* has a native in-box USB 3.0 driver.
since we're unable to to install the driver via Windows update or download it from manufacture website, but the driver must be corrupted in your system for some unknown reason, so I suggest you return the system to a previous point at which everything is
function fine with restore point.

Making a Windows 7 Installation USB Stick

This is a discussion of making a bootable Windows 7 Installation USB-stick Media. It might apply to making other USB connected "Disks" like Smartcards bootable too.
I recently had to do this (a Laptop with no build-in DVD drive and no USB DVD drive around). And it turned out to be surprisingly simple, using nothing but build in Windows tools from the Disk. I only found
this german langauge guide and nothing in english (but I might just have searched after the wrong terms, google has been wierd regarding langauge lately), so I thought I write it up (along with some problems I ran into).
Making a USB-Stick into a bootable Windows 7 (and propably Vista) Media is a 3 step process:
1. Create a Active, Primary, FAT32 Partition of 4+ GB on the stick
2. use bootsect.exe from Windows Disk to create the MBR and Partition Boot Record for that Partition
3. Copy all files from the Disk to said Partition
4. Test if it boots
Detail analysis:
Step 1 is so simple I doubt it needs explanations. Create enough free space on the USB disk (at worst delete all previous Partitions). Make a Priamry Partition of 4+ GiB. Mark it as Active. Format it in FAT32. The Guide used Diskpart,
but this step can be done with any Partition Tool under any Windows, Linux, UNIX or DOS.
While the choice of FAT32 seems a bit outdated, theye propably did not gave the relevant bootlaoder the ability to read NTFS. Or maybe they just though FAT32 is enough for a media that is mostly read. I have not tried what happens if I format it in NTFS, but
it might be possible.
Step 2 was the only tricky part. You need the programm "boot\bootsect.exe" from the Installation Media. It also must be run on a non-UEFI booted OS (otherwise it cancels out).
I had a Windows 8 on a new Laptop so I had a UEFI booted system. Luckily I also had a VMWare Windows 7 lying around. I just assigned the Windows 7 ISO image to the Windows 7 VM, then connected the USB drive to the host.
Once you have the USB stick in a a proper Windows mount the Parttion you created under 1 under any driveletter (should happen automatically under Windows), and open a console as Administrator (asumes DVD is drivletter is D: and the USB stick's partition
ins Driveletter E:):
//Go into the boot directory on the Install DVD
D:
cd boot
//You should see a command promt like "D:\BOOT>"
//Run bootsect.exe
bootsect.exe /nt60 d:
Step 3 is to either copy the contents of the DVD media (copy and paste) or the Image (Mount into Virtual DVD Drive and copy/paste, unpack ISO images contents) into the partition.
How does this compare to other Distribution ways?
To DVD:
There is no need for a DVD drive. Even if a bootable USB-DVD drive is avalible, the Stick or Card will only need only USB port (most USB drives need 2 Ports due the 1 Ampere energy need of the drives).
Flash Media has no seek times and much better throughput (the old weakpoint of any Disk and DVD/CD in particular)
A FAT32 partition is inherently writeable. So modifications to the "Installation media" like Implementing Service Packs and other Windwos Updates, Modifying ei.cfg/preactivation/setup answer files, implementing special Disk/RAID drivers into the Windows
PE or adding stuff that should be installed with Windows is easy (and do not requrie reburning a 4 GiB Image file).
Since it only needs a 4 GiB partition, on a big USB stick there would still be place for other Data Partitions
Since it relies on old techniques (Generic Bootloader + Active Primary Partition + partition boot loader), multiple Installation media on a big enough stick might be feasible (with a more advanced bootloader like GRUB). Have to test that part.
However, the cost/media is a lot higher then a DVD. So if you need multiple Medias it will propably be cheaper to use the old DVD approach.
Due to the needs of bootsec.exe, first creating the media can be more difficulty then just burning an image. But once it is bootable this programm is no longer needed.
To PXE/network Distrubution:
If you have the nessesary setup already (DHCP/PXE Server, powerfull network), the USB stick is likely inferior. The USB stick should beat a 100 MBIT Network easily, but will propably be beaten by a 1 GBIT Network. Network isntallation uses existing infrastructure
(that you need for other reasons anyway) so the cost per media is even lower then the DVD.
The PXE way also has even better modifyability - sending out different answer files or even automatically booting different images based on the Compuers MAC adress are tried techniques.
If you lack the nessesary setup, the USB stick is a lot easier to implement and a lot easier to transport.
Advanced things:
Need to check if the partition could be formated as NTFS. I prefer a Journalling Filesystem for my USB-sticks.
Need to check if using a advanced boot manager techniques (like Grub or modifciations to the BCD of the Windows PE) allows me to put multiple install media on one Stick (with one primary partition per "media"). Especially combining the x32/x86 and
x64 Windows Installation Media would be worthwhile. As would be inlcuding a Window 8 or Vista installation media.
Current Step 3 and 2 can propably be switched. I see no reason bootsect could not run from the USB stick as it runs from the DVD (it only accesses the MBR and
VBR of the Disk, areas not in use by Windows)
Steps 1 through 3 might be possible from the Windows PE environment. If so, only a computer with legacy BIOS boot would be nessesary (no actuall installation).
Windows 7 can be installed on a (U)EFI system, but I have not checked if I can use the boot from teh stick on such a Computer. Latest for Windows 8 Media UEFI compatibilty is nessesary.

I converted the stick to NTFS using the convert.exe and it continued booting. So chances are high they only choose FAT32 in the example because no feature of NTFS was per nessesary in a "almost only reading" scenario like installation media.
The second part depends on the BIOS. I have a more advanced one where I can choose legacy boot options (like USB stick) in the boot option menu even when the default setting is UEFI, as long as I don't need Secure boot (wich I do not).
Another question arose: Windows 7 has the Kernel/BCD level ability to boot from .VHD Files. The only thing preventing version below corporate from using this feature is a license check that is run just before the login (so way after the booting has been
completed).
Starting with 3.0 Windows PE is based on the kernel of Windows 7. So the instlaltion system might have the ability to boot from .VHD too and might have no such check in place. If so, I could put both versions of the Windows 7 installer into .VHD, reducing the
need to have physical primary partitions for those.
Windows bootprocess vs. Linux boot process under BIOS:
The BIOS goes over all the boot media. If it finds one with a MBR, that one is executed and the BIOS part of the boot process is officially over.
-> Under Windows the MBR contains the "generic boot loader". A simple piece of code as old as BIOS (25 Years) that looks for the primary partition with "Active" Flag on "it's" disk. If it finds one, the Partition Boot Record of that parition is executed.
The MBR has done it's part
    -> NTLDR (NT too 2000), this one reads the boot.ini file and gives/executeds apropirate options
    -> BOOTMGR (Vista, 7), this one reads the BCD files
      -> Since Windows 7 BOOTMGR can also chainload the Partition Boot Record that is inside a .VHD File
    -> Wicher was used in Windows 3.X/95/98/ME
Higher versions can chainload lower versions, but must be designed for this and (re)installed in the proper "order".
The sometimes odd behavior that Windows 7 tries to keep 100 MiB in a seperate primary partition is there to have proper places for later additions to the BOOTMGR settings. Specifically it allows multiple BOOTMGR OS to use/edit the same BOOTMGR instace without
running into problems with "whose partition is active?" (since it is always the System Reserved one). It's not disimilar to having an extra /boot partition in Linux or how a GRUB's stage 2 works.
-> Under a typical Grub Legacy the MBR contains the Stage 1. It directly reads the Stage 2 from the proper partition/file system with a hardcoded path, but due to size limit of the MBR cannot do more. In some cases it starts a stage 1.5 wich has more
space to do work (63 sectors between MBR and first partition), but I never used this Setup
    -> Stage 2 loads the Grub Configuration from the disk. From here it depends on what OS you want to boot.
        -> For Linux or Unix the kernel is started directly.
        -> Any Windows OS up to 7 can be booted using the chainloader command. For the OS this is identical to having the partition choosen by the Generic Bootloader.
While it can be chainloaded by the Generic Bootloader from the active primary partition, GRUB and thus Linux has no
requirement for any Primary Partitions. Stage 1 is designed to directly access the specific File System containng the Stage 2. In fact it does not even need to reside on the same disk (as the Generic Bootloader has to).
If one does not need the Active Flag to control the Generic Bootloader (because a proper Stage 1 is installed in MBR) it is adviseable to mark wichever Windows Partition is chainloaded as active (up to Vista at least I had very odd behavior if the Windows boot
partition was not marked active, down to randomly shredded Partition boot managers).
After running a Windows Setup usually the Stage 1 has to be restored, as Windwos Setup will always write it's Generic Bootloader in the MBR. In order to get "rid" of a Grub all one has to do is overwrite the MBR with the Generic Bootloader and set the active
flag properly.

Windows 8 Recovery USB causes UEFI error: "Grub error: Can't find gpt 7" [FIXED]

Hello everyone,
Here is my situation. I had a dual boot setup on my toshiba S855D (Win 8/Ubuntu 12.10). After a few months my win 8 install was giving me strange errors. I decided to do a full reinstall using the recovery USB I made. (I had reinstalled once before) When I plugged in my USB after restarting the computer (in USB as first boot), I got the error: 'Grub error. Can't find gpt 7' If I tuned off UEFI, the computer could at least detect the USB but not do a reinstall. Thinking it was a Grub error I formatted the HD (using an ubuntu liveUSB). The problem persisted. I installed boot-repair on ubuntu and tried that, but no effect. I have tried to install an updated bios from the CD image in the bios zip, but it wouldn't execute the commands in the ini file. I even tried to install an old xp disk I had to see if I could install the bios update that way, but the windows install repeatedly froze.
Quick version: dual boot (win8/ubuntu)->try to reinstall win8, "error: Grub Error: Can't find gpt 7", when usb is attempted to be booted from. ->Wiped hdd, but problem persisted. -> tried many ways to fix, but nothing works.
I have been reading many forums for the past few days, and nothing looks to work. Any and all help would be really helpful.
Solved!
Go to Solution.

I finally got it!
After much poking around the internet, I was finally able to identify my problem. My bootx64.efi in the EFI/Boot folder wasn't working. I found this out by putting UEFI shell on another usb and using that to test my *.uefi files. Thankfully, I had a backup of my EFI folder from my initial Ubuntu install. This had a backup made my ubuntu. (bkpbootx64.uefi) I ran the backup and the USB worked!
On another forum someone (Agent268) said this, which may help. I'm guessing you need to have a windows pe DVD/USB to make this work though.
"You should be able to use DISM to manually reimage this bad boy using the WIM or SWMs on that USB recovery flash drive."
Hope my research helps someone out there. Cheers to everyone who looked.

How to boot from Windows 7 installer USB-thumbdrive?

I have created a Windows 7 installer USB-thumbdrive from .ISO image using Boot Camp Assistant.
What I can't figure out how to make my Mac Mini boot from USB to start the Windows 7 installer. The USB-thumbdrive does not show up in the boot menu when pressing ALT during startup (I'm using generic PC keyboard) nor is it available for selection in System Settings --> System --> Startup Disk.
My computer is early 2009 Mac Mini, Intel Core 2 Duo, 4Gb RAM, OS X Mountain Lion 10.8.4.

Anyone?
Additional question: is a 2009 Mac Mini able to boot from USB to begin with?
The situation has become particular annoying, because my Mac Mini's optical drive appears to be damaged and therefor I'm not able to boot from any kind of Windows install DVD.

USB 3 Instability Issues - Windows 8.1 - Windows 8, The USB 3 Stack Is Unstable On Multiple PCs And Many Devices

The USB 3 stack is unstable in Windows 8.1 and Windows 8. I was hoping the upgrade to Windows 8.1 would improve the stability but no.
On two different motherboard systems I have had the same experience with 64 bit Windows 8 Pro and Windows 8.1 Pro compatibility with various USB 3.0 devices and hubs including:
An AFT PRO-57U front panel card-reader/hub, various Anker, Syba multiport hubs, and these are just a few I have tried, there are many more.
Symptoms are the same.
For example: the AFT PRO-57U slots are enumerated correctly as drive letters in Windows 8.1.
Then the drives (the PRO-57U slots) disappear, then reappear, then disappear, and reappear and so on. This happens consistently and the cycle time to disappear/reappear varies from 10 seconds to 10 minutes.
The Windows Device Manager shows the devices appearing and disappearing as enumerated devices. I have tried many trial and error methods to solve this, uninstalling and reinstalling USB motherboard drivers, different cables to the AFT PRO-57U device different
USB 3 ports for the devices and many more...
One of the hubs I bought specifically because it has the latest chip and firmware: Anker® USB 3.0 9-Port Hub + 5V 2.1A Smart Charging Port with 12V 5A Power Adapter [VIA VL812-B2 Chipset and updated Firmware 9081] This hub FAILs to enumerate some external
HDDs and other devices.
To troubleshoot I have tried many things:
I have disabled Windows Power Options, USB Selective Suspend.
I have disabled power options for each and every USB device in Windows Device Manager
I have uninstalled the Asus AI Suite 3 software and the issues remain.
I have tried BIOS settings for Legacy USB devices on and off and the issues remain.
I have tried BIOS setting for xHCI Mode - Auto, Smart Auto, On, Disabled
I have updated to the latest Intel chipset drivers 9.4.0.1026
I have all the latest BIOS, drivers, firmware, devices, - anything that is involved with the USB 3 stack.
Etc. etc. etc...
I have contacted Asus, Gigabyte Intel, AFT, Anker Syba, etc. and they are all finger pointing.
I have tried so many trial and error methods to solve the problem and I have run out of ideas.
It is clearly an unstable USB 3 stack and I am not sure who is responsible although I suspect Intel chipset drivers.
USB 2 is fine BTW. All devices work correctly when plugged into USB 2 ports.
From what I can tell, the entire USB 3 environment is a problematic P.O.S.
If anyone has any ideas I am willing to try anything I have not already tried.
Thanks,
Michael Downs
P.S. Here is my system information. I have all the latest BIOS, updates, drivers and etc. for all devices.
ASUS Maximus VI Formula w/ BIOS 1002
Intel Core i7-4770K BX80646I74770K
G.Skill Trident X 16GB (2 x 8GB) DDR3 2400 Model F3-2400C10D-16GTX
Samsung 840 Pro 256GB SSD Seagate Constellation CS ST3000NC002 3TB 7200 RPM 64MB
EVGA GeForce GTX 760 ACX 2GB 256-bit GDDR5
Corsair Carbide Series 330R Mid-tower Case
Corsair RM850 850W 80 Plus GOLD Certified
Cooler Master Seidon 240M - Liquid CPU Water Cooler
Pioneer 15X BD-R SATA Blu-ray Burner BDR-2208
AFT PRO-57U All-in-one USB 3.0 5.25" Media Card Reader
Then there is a similar system with the exact same USB 3 issues:
Gigabyte - GA-Z77X-UP4TH
Intel i7 3770K
etc.

Hey, I hope this helps you out a bit... I have had the same issue on my Asus K55A notebook with Win8.1 Pro x64 from the beginning! Thru my extensive research I found something interesting and the possible cause to all this! What I found was that by design
the xHCI Host Controller has virtual HS 2.0 Ports linked to the 3.0 Ports... Enabling compatibility with 2.0 devices ok... What happens is that the xHCI stack is unstable just like you say... The ONLY WAY I was able to fix the problem was by unlocking the
UEFI/BIOS to allow me full access to USB Configurations... I had to disable 2 of the HS ports under the xHCI Controller since I have only 2x 3.0 ports... This allowed 3.0 devices to be enumerated correctly under the xHCI stack and 2.0 devices now were enumerated
under the EHCI 2.0 stack... That's what worked in my case... I'm still digging around for more info about this issue because I find it so odd that no one discovered this when designing xHCI stacks and drivers at MS for Win8/8.1 x64... I hope I shed some light
on this issue... Good luck and keep us posted!
Hi, Sebastian. I have the same problem but i'm getting crazy trying to solve it. Can you help me to unlock the UEFI to access full USB config? and give me some suggestions on how to solve the problem?

Welcome to Apple Support Communities
You can install Windows from a USB drive in one of these computers:
- MacBook Pro with Retina display.
- Mac mini (Mid 2010 and newer).
- MacBook Air.
- iMac (Late 2012).
If you don't have any of these Macs, you can't install Windows through a USB drive. Instead, buy Windows on a DVD. Follow Apple's steps > http://support.apple.com/MANUALS/1000/MA1519/en_US/Boot_Camp_Install-Setup_10.6. pdf

You can only install Windows from a USB with one of these Macs:
- MacBook Pro with Retina display.
- Mac mini (Mid 2010 and later).
- iMac (Late 2012).
- MacBook Air.
If you bought Windows in Internet and you got it in a ISO image, you can burn it into a DVD. Simply double-click the ISO image, open Disk Utility, right-click the ISO image in the sidebar and burn it

Installing Windows 7 from USB flash (Macbook Air mid 2012)

Hello,
I read some famous instructions, but they are not for Macbook air mid 2012 as there are some missing options in their Bootcamp Assistant and this on macbook air 2012.
Btw, they suggested some rEFIt program which supports installing windows from usb which is made in 2010 but it has not been updated since then. I tried it but it doesn't work like it is described in instructions.
I have my USB and Windows 7 on it, but i don't know how to install it on the Macbook Air 2012.
Any help will be appreciated.
Kind Regards,

Hello,
Thank you for the explanation that helped me to understand Windows 7 installation process!
Unfortunately i need more additional information as Boot Camp Installation & Setup Guide is very poor with information that i need.
To explain you better what i mean on, i will quote Boot Camp Guide parts with underlined sentences that have been confusing me. Some sentences that have been confusing me more than other ones will be additionally bolded. I will explain you why i don't understand it after every part.
1. "Introduction"
"You can install Windows with an installation disc you provide or, on some Mac computers, with a USB flash drive that contains a Windows ISO images downloaded from Microsoft. Boot Camp Assistant helps you burn the image to the flash drive."
-But i already have my iso image on the USB flash drive. There is no need to be burned again?
2."What you need"
"Boot Camp Assistant erases the flash drive, and copies to it the Windows 7 ISO image and software drivers that let Windows work with your Mac hardware."
-Erasing the flash drive? Does it mean that it will delete my WIndows 7 which is already on my flash drive?
-Copying Windows 7 ISO image and software drivers to my flash drive? Why? I already have Windows on my flash drive! Software drivers? How do i get them and where shall i place them?
3."Prepare your mac for Windows"
"If you want to install Windows from a USB flash drive and you have a Windows 7 ISO image, select option to copy the image to a USB flash drive."
Why shall i select the option to copy Windows 7 ISO image?
1.I already have it on my flash drive.
2. I don't have it on my Macbook so there is no place in a ssd where Boot Camp will find Windows 7 ISO image.
Here is the overview:
Guide is telling me to select the option to copy image to a USB drive which will first erase my USB flash drive and then copy Windows 7 and it's software drivers to my USB flash.
-But only thing that i need is Windows support software and i don't know whether to download it to desktop, or to USB flash drive.
Kind Regards,

Can't boot from windows 7 install usb drive created in bootcamp

So, my real problem is that my Windows 7 install won't boot after I installed some windows updates. I'm using OSX Lion and the latest version of Bootcamp. I've had Windows installed on my mid 2011 mac mini for only about a day. It had been working flawlessly so far.
Windows automatically downloaded and installed some updates and now it is broken.
When I attempt to boot windows I get a black screen that just hangs forever. No windows logo, no blinking cursor, no nothing.
I thought I could use my Windows 7 Install usb drive to maybe try and do a recovery or repair install but now my USB drive wont boot either. I get the same black screen.
Any ideas on why I can't boot even the install usb drive?
Note: this is the same USB drive I used to install windows the first time so it's definately capable. I've even used my install iso to re-create the usb drive installer and still nothing.

Install ISO means you burned DVD installer and did you reduce burn speed? otherwise it is a bad install.
3rd party updates? for security suite? stick to MS Security Essentials instead.

Connecting my gen 4-5 nano to new HP laptop windows 8 using USB 3.0 port computer restarts

Connecting my gen 4-5 nano to my new HP laptop Windows 8 using USB 3 port itunes opens then an error message "your PC ran into a problem and needs to restart ........." WDF Violation. If I don't disconnect the nano the computer will keep restarting. After restarting a window opens saying it wants to send the following files to Microsoft "C:\Windows\Minidump\010413-20875-01.dmp, C:\Users\Curt\AppData\Local\Temp\WER-69015-0.sysdata.xml, C:\Windows\Memory.DMP". It does this using any of the 3 USB 3 ports. Using the USB 2 port it works just fine. Thanks for any help and as info.

I found the solution!!! Even ended up educating the tech -- who didn't have a clue.
I have a brand new 7th gen iPod Nano, a brand new Windows 8 laptop, and iTunes 11. Everything was working all fine and dandy until I unchecked "Enable Disc Usage in iTunes on my iPod. Then all **** broke loose. I got the blue screen of death with the WDF_violation and I couldn't even plug my Nano in without it crashing my computer, let alone access iTunes to re-enable Disc Usage. Because the crashes happened immediately after I did that I just KNEW it had something to do with that. Trouble is, I couldn't fix it.... or so I thought.
I was on the phone with the tech, who was telling me it was a driver issue ( impossible because both the laptop and iPod are brand new) and I was looking around in iTunes while she did.

Hi all,
my usb 3.0 port worked fine in windows 8,, then updated to 8.1 and 8.1 update 1.
Then I had to run a system restore (to a point in time 24 hours before), and then... boom:
No device is detected anymore on the usb 3.0 port of my laptop.
No usb key, no disk... the usb 3.0 disk light turns on and it's blue (3.0) but the device is ignored by windows: no error
in device manager, just nothing.
The only thing I noted, is that when I insert anything in that port, the system interrupts entry of the task manager spikes
to 17% and stays there forever, until I reboot.
I've tried everything I could find on the web for 2 days, I'm probably giving up and will disable the "Intel (R) USB
3.0 eXtensible Host Controller -0100 (Microsoft)” entry in device manager.
I can't believe it's a hardware issue... but it behaves as if it was. My UEFI is very simple and there are no settings for
usb, and the issue persists in safe mode too.
Any idea?
Thanks

Hi,
Please check Device Manager if there was any error message with USB 3.0 driver. If so, what's the error code of it.
