Bootable ISO not recognized by Hyper-V on Win 8.1 Enterprise 64-bit - VMware Workstation understands perfectly

I activated Hyper-V on my fully patched Windows 8.1 Enterprise 64-bit host PC and tried to create a Windows Server 2008 R2 virtual machine that should have installed from the bootable ISO (the one I downloaded from my MSDN subscription) for Windows Server
2008 R2, but when the VM starts, it goes through its boot device progression and fails to recognize the ISO as bootable. No amount of coaxing will convince Hyper-V to use the bootable ISO to install the operating system in the VM.
To see if there was an issue with the ISO, I removed Hyper-V from the host (because, as I discovered, VMware refuses to run when Hyper-V is present) and then fired up VMware Workstation 10, pointed it to the exact same ISO and it created the VM from that
ISO just fine. That proves there is nothing wrong with the ISO image.
I'm new to Hyper-V since I've been using VMware Workstation for quite some time and figured it was high time I began to make the switch to Hyper-V (since I'm paying for it anyway).
What setting(s) do I need to adjust to insure that Hyper-V sees the bootable ISO properly so it will install that OS in the virtual machine?
If you think development is tough now, think how hard it was using punched cards :-)

I followed the Hyper-V wizard instructions to the letter, including telling it the full path to where the ISO I wanted to use in creating my very first VM is located. I assume (perhaps incorrectly) that the Hyper-V wizard mounted that ISO on whatever
device it deemed appropriate, hopefully one that is in the boot device sequence. It all was very straight-forward and easy to understand; however, it doesn't work.
The corresponding wizard in VMware Workstation 10 fully understands the ISO and proceeds with its "Easy Install" process without anything else except the license key.
I didn't capture a video of the failed Hyper-V boot process, but to summarize, it went through its "progression" of devices and simply never found the ISO that I had previously designated.
Despite its seeming simplicity, the Hyper-V creation wizard doesn't perform what it is instructed to do while the equivalent VMware Workstation 10 wizard works flawlessly.
If you think development is tough now, think how hard it was using punched cards :-)

Windows 8.1 64-bit ISO Not Recognized in Bootcamp

I am attempting to install Windows 8.1 64-bit via Bootcamp on my mid-2010 15-inch MacBook Pro, but the ISOs and bootable USBs all include both the 32-bit and 64-bit versions of Windows 8.1 and I receive an error message "Bootcamp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation." It appears that Bootcamp is detecting the 32-bit version and ignoring the 64-bit version so I am unable to install.
I have tried editing the Bootcamp Info.plist to make my MacBook Pro (MacBookPro6,2) eligible for the 32-bit installation, but the error still appears.
Does anyone have a solution for how I can install Windows 8.1 with Bootcamp?

I get the same error, but I'm using a 64bit only Windows 8.1 ISO and different target hardware. I haven't found a workaround anywhere. I'm trying to install Windows 8.1 on a new iMac 5k* using the Bootcamp Assistant Version 5.1.2 (497) included with Yosemite 10.10.1. I bought Windows 8.1 on a Windows 7 PC and used Microft's mediacreationtool.exe utility to create the 64-bit-ONLY iso. The utility allows you to select the Edition of Windows 8.1 (vs 8.1 Pro), the language, the architecture (32bit x86 or 64 bit x64), then you can select the media type: bootable USB or ISO.
i Selected the English 8.1 64bit ISO and copied it over the LAN to the iMac since it doesn't come with an optical drive.I launched Bootcamp Assistant and che ked all 3 available Checkboxes as described in the instructions, browsed to the ISO image, selected the FAT32 formatted USB stick and clicked continue, that's when I get the error about 64 bit Windows is required, the same as the title of Bill W's post above.
I Created the ISO again just to make sure 64 bit was selected and got the same results. I Rebooted, same result. Others said they just copied the ISO to their documents directory and that fixed it, not for me. Others said they just had to rename the ISO to DMG, that didn't work for me either.
In another article here, someone suggested modifying the info.plist for Bootcamp Assistant, I tried that, same result as several others, problems with unlocking and replacing the edited .plist file.
When I examine the files in the ISO on the PC, there's nothing to indicate that there are two builds to support both Windows architectures. Other people claim they've installed Win 8.1 on this hardware successfully using the same technique.
Any ideas? Any additional info required?
Thanks in advance! Is there a way to cross-post this in other forums or threads if this is not the best place for it?
Matt
*My iMac is close to its factory state (I some App Store apps), iMac (Retina 5K, 27", late 2014, Model ID 15,1), Yosemite 10.10.1 (Build 14B25), i7, 3Tb Fusion, 32Gb RAM, 295M w/ 4G, SanDisk Cruzer Edge Media brand USB memory stick with 16Gb for use with Bootcamp. 1Tb free space on Fusion drive, was planning to allocate 100Gb out of that for Windows.

5th generation IPOD not recognized by computer

Hey Internet users, my dad's been having some troubles and I was hoping to try and help him by reposting something he did elsewhere...
"Hello Everyone and thank you for reading my post.
I have a weird problem, my 30 gig 5th generation Ipod is not recognized by my computer or itunes. This is the last thing it happen, I was working on a client house for days, so my ipod's battery was completely dead, I was kind of desperate, so I thought that I could plug it to my client's mac just to recharge, but nothing happened. So days later I got back home and my windows PC will not recognized or charge the ipod at all. I got it charge and works perfect with my Ihome radio. I tried rebooting the Ipod, I tried resetting it to be in disk mode with not a problem, I tried changing the USB port, I did connected my friends Ipod and connected right away, so the wire connector is OK, I tried a different wire connector just in case, I tried connecting the ipod to a different PC.... I kind of running of ideas here. The ipod works great but I would live to download some new tunes to it... Any ideas. I cannot restore or upgrade firmware because ipod is not recognized by the computer....
The thing I am trying right now is installing the latest Itunes and see what happens. I have windows Pro SP3 recently updated. Your help would be greatly appreciated."
So...if anyone has any ideas, please post!!

I am having the same problem. Sorry I'm not going to be of any help. But I hope someone gives you some recommendations cause I really want to get mine fixed. My iPod did the exact same thing. It was dead and I tried to use my car charger for the first tim and it did nothing. Then I plugged it in to a friends computer and nothing. I can only charge it on a speaker dock. And no computer recognizes that it's connection when I use the USB cable.

Guest executed an intercepting instruction not supported by Hyper-V instruction emulation; event ID:18570

Hi, Just started to play with Hyper V on win 8.1 enterprise, before this I was using VPC 2007 for (32 bit guest) and vmware (64 bit guest)
Here is the problem I have, I have windows 7 32 as a guest running till date using vpc 2007, now I am trying to use the vhd file in hyper v
Option 1
Tried configuring the same vhd file in hyperv by uninstalling (addins) and removing network card configuration and shared folder
Option 2
Tried converting vhd to vhdx using hyperv gui and ps command line
In the both the options when I start the vm on hyperv, the cursor just blinks
In the event log I get to see this, any solutions for this would be of great help
'abcd' was faulted because the guest executed an intercepting instruction not supported by Hyper-V instruction emulation. If the problem persists, contact Product Support. (Virtual machine ID E965D4B5-E976-45FD-B004-F51C12662360)

Uninstall the VPC VMAdditions from within the VM - they are trying to do something that Hyper-V does not allow.
Hyper-V is not Virtual Server and the Virtual Server VMAdditions are not compatible with Hyper-V.
Also, you have to set the HAL to re-detect. VPC relied on a custom HAL, and if the OS in your VM is old enough, it won't automatically detect the change and will continue to use the VPC compatible HAL.

Mac Pro not recognizing bootable DVDs and Disk Utility giving odd results.

My issue is complex, but I'll try my best to explain it as I can.
One has been resolved it seems, but I am including it so that the whole issue can be seen in context.
Friday, May 16, 2014
Last night, after rebooting my Mac Pro from my Bootcamp partition (I'm using Windows 7 Professional if that information is helpful) I received a kernel panic upon Mac OS X booting (Mac OS X 10.6.8).
My first action was to launch Disk Utility to verify the Mac HD, verify was stopped by disk utility citing that I should insert my Mac OS X install DVD and repair the disk.
I tried booting from my Snow Leopard install DVD. After the grey Apple logo appeared with the gear spinning below it remained for roughly ten to fifteen seconds (a little long) — then the Apple logo changed to. A grey prohibitory sign (circle with a diagonal line through it, the spinning gear remained. — I tried booting from the Snow Leopard DVD a few time, same result.
Following this I tried booting using Disk Warrior, same result again.
I tried booting both the Snow Leopard and Disk Warrior DVDs in both my upper and lower optical drives, with no change.
I decided to leave the issue and call Apple Support in the morning
Saturday, May 17, 2014
This morning I woke my Mac Pro from sleep, opened Disk Utility and tried verifying the hard drive to see if it was temporary — same result, 'please insert the Mac OS X install DVD and repair the drive.' — I also tried booting the install DVD again with no result.
I then booted my Mac into Safe Mode to check my hardware.
Upon opening Disk Utility and verifying my Mac HD — the result "Macintosh HD appears to be OK", rand the test again to see if this was an anomaly, but disk returned another pass.
I performed a normal restart of my system, although Finder was a little slower to load than normal, the system booted correctly. — I then launched Disk Utility and verified the Mac HD, it returned another pass.
This confused me, after a call to Apple Support the tech explained that 'sometime a Safe Mode boot will fix problems because it disables all non-essential processes when booting. — That makes sense to me.
However.
The issue of my Mac not recognizing bootable DVDs remains — it reads disks correctly, it just will not boot them.
Other steps I have taken to try and resolve this remaining issue.
1. a PRAM reset. — No change.
2. an SMC reset. — No change.
3. Removal of newly installed RAM. — I have tried both running the old and new RAM separately, no change using either combination.
4. Running bootable DVDs in different optical bays. — No change from both bays.
a. My upper drive is an MCE Blu-Ray/DVD combo drive, but I have booted from this drive before. (Less than six months old.)
b. My lower drive is LG DVD-RAM combo drive, I have also booted from this drive before. (Over one year old, replacement for an Apple optical drive.)
None of the above steps have helped, I still cannot boot from my optical drives — I always receive a prohibitory sign shortly after the Apple logo.
Other system information:
Mac OS X 10.6.8
8GB of RAM (4 x 2GB)
500GB Western Digital Caviar Blue HDD (less than a year old, boot drive for Mac OS X 10.6.8)
1TB Samsung HDD (for data storage and also containing Bootcamp partition)
2TB HDD (cannot remember manufacturer, contains Time Machine backups, as well as data storage)
ATI Radeon HD 5770 with 1GB of VRAM
Sorry for the long post but I really need to be able to boot from my optical drives.

Update: found an old Mountain Lion installation USB flash drive I created a while back.
I am able to boot from the ML USB flash drive, but am still unable to boot from my either my Snow Leopard Install DVD or my Disk Warrior DVD. — I have verified both DVD and they pass verification tests.
This leads me to believe that the problem resides either in the Mac, or in BOTH the Snow Leopard and Disk Warrior DVDs.
Since I am able to boot from a USB drive, I will look into the possibility of creating a bootable Snow Leopard drive, and perhaps also a Disk Warrior drive — at least until I can resolve the 'not able to boot from DVD' issue.

XP Prof installation on Tecra A9 PTS52E - SATA HDD is not recognized

Hi all,
I have a brandnew Tecra A9 (PTS52E) with Vista Business installed. However, I need XP Prof and have a slipstreamed XP-SP2 CD. The SATA Disk is not recognized from XP setup, so I need a 'F6' driver.
There are a lot of howtos about doing this for the 945 chipset, but I couldn't solve this on my A9 (Mobile 965 Express Chipset). I don't want to buy a USB-Floppydisk drive just for one-time-installation. So I have to build the driver (iastor.sys and more) in the XP setup disc.
Some problems: there seems to be no easy way to do this, because intel only provides *.inf files for the ICH8R (=RAID) controller, which doesn't exist in the A9. So I have to edit the *.inf files, correct?
Another thing: I saw in another posting here the discussion about switching from AHCI to compatibility mode in BIOS. I can't find a way to change this setting.
Aargh, I need this Notebook for my work, on a A8 (which also is mine) I installed XP without any problems.
Can anyone help?
Thank you,
Michael

Hi,
now i have a new problem: the last reboot after installation finished leads to bluescreen and immediately reboot (so I can't see the stop-message)
During installation the reboot from Harddisk works.
But so far:
you need the latest Intel Chipset Driver:
http://downloadcenter.intel.com/T8Clearance.aspx?url=/13499/a08/infinst_autol.exe&agr=N&ProductID=2800&DwnldID=134 99&lang=deu
Next you must extract the files in a temp directory:
IATA75 _ENU.exe -a -a -pC:\temp\AHCI
Now edit the file iaahci.inf:
you have to change all the ICH8R related entries (R means RAID, which isn't supported in that A9 version of the chipset) to ICH8. Also change the related PCI-device IDs from 0x8086h/0x2821h (Vendor/Device ID) to 0x8086h/0x2824h.
The best way I think is to copy all ICH8R related sections and replace "ICH8R" with "ICH8" and "2821" with "2824".
As you need the driver during installation, you also have to change these settings in txtsetup.oem.
The next steps I found in a ASUS forum (they have similar problems):
create a new (personalized) installation CD for Windows XP
STEP 1: Modify the original XP installation files
a) Copy all the files and directories of the XP installation disk to your hard drive
Ex: form D:*.* (your installation CD) to C:/XP/*.* (your HD)
b) Create the following directory path:
XP\$OEM$\$1\drivers\SATA
c) Copy all the files of the Intel Matrix Storage Manager (see solution I) to that directory: XP\$OEM$\$1\drivers\SATA
iaAhci.inf, iaAhci.cat, iaStor.inf, iaStor.cat, iaStor.sys, and TxtSetup.oem.
d) Copy iaStor.sys to XP\i386 directory
e) Modify the file TXTSETUP.SIF located at: XP\i386
=> You can read and understand what you are doing reading Adding OEM drivers to Windows Setup at http://www.windowsserverx64.com/CSK/technical_articles/hardware/56.aspx (really nice article form Robert. Thanks)
Use: notepad.exe to edit it.
e.1) Under [HardwareIdsDatabase] add the following lines
right after GenFloppyDisk = "flpydisk"
PCI\VEN_8086&DEV_2821&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_2824&CC_0106 = "iaStor"
and before PCI\VEN_8086&DEV_1230 = "intelide",
Note: dont touch any other line. Be carefull, the name iaStor => is case sensitive.
e.2) under [SourceDisksFiles] add
iaStor.sys = 1,,_x,4,1
Note: There are several [SourceDisksFiles] sections. I added the line in all the existing sections.
e.3) under [SCSI.Load] add
iaStor = iastor.sys,4
e.4) under [SCSI] add
iaStor = "Intel(R) 82801HEM/HBM SATA AHCI Controller (Mobile ICH8M-E/M)"
Note: If your controller is a different one, use the right one. Read the contents of the TxtSetup.oem file for more information.
f) Create a new file called (use notepad) WINNT.SIF and locate it at: XP\i386

Now use a tool to create a bootable CD. I prefer "AutoStreamer" because I also have to slipstream SP2 into my XP Prof. CD.
With it you generate an iso image. Burn it to disk and that's it.
Like I've said: installation works well, just the last reboot from disk creates a bluescreen and therefor a bootloop.

Michael

Copy of a CD (created by Disk Utility) not recognized by Windows or Linux

I created a copy of AutoCAD 2005 (not pirating it... just wanted a backup copy of the install CD).
I used Disk Utility (File > New > Disk Image From Folder) to successfully create a DMG file on my MacBook. I could mount the DMG and browse all the files on it.
I then burned a CD (Disk Utility > select DMG > click burn), which mounts fine on OSX. However, my Windows and Linux boxes will not recognize it (while they recognize the original CD just fine).
I tried again, this time setting the file format to DVD/CD master. It made a CDR file, which I burned to CD. Got the same result: Windows and Linux don't recognize it while OSX does.
So instead I burned the files to a CD ala drag and drop using Finder. This time the CD was recognized by Windows and I used it to install AutoCAD.
However, my understanding is that doing it this way won't work for a bootable CD, so I'd like to figure out why Disk Utility wasn't able to make an exact copy.
Any thoughts? Problem with copy protection? Problem with the CD's file system?

Yeah OS X's Disk Utility doesn't burn using the ISO 9660 file system while Finder does (I could swear I made a copy of an MS Office CD with Disk Utility, but maybe I'm remembering wrong). Anyway, Disco (a program I got in a MacHeist bundle) will make an exact copy of CDs. Anyone looking for a free solution, check out LiquidCD and burn, which may have the ability to copy Windows CDs (appears to be on their lists of features, but I haven't tried them myself).

External hard drive is not recognized after attempt to format

I just got a new macbook and couldn't use my external hard drive because it was formatted on a PC and only allowed me to read the data. I backed up the data on the 250gb hd and then used Disk Utility to erase the hd and format it as "Mac OS extended (journaled)." After beginning, Disk Utility stopped working and showed up as "not responding" in the Activity Monitor.
Now the hd does not show up on the desktop and can only be seen in Disk Utility. If I try to erase again or partition the hd the utility stops responding. If I try to zero out the drive it continues to say "preparing to zero" indefinately. Now the hd is also not recognized by windows except in the windows disk utility, but it does not even give the option of formatting/initializing it, so that is not an option.
Has anyone ever seen anything like this before, or have any idea of something that I haven't tried yet. I really want to get the drive working and have exhausted all the ideas I can come up with. The internet has not provided too many ideas either.
Thanks so much for your help.
Black MacBook Mac OS X (10.4.6)

I have crazy solution to format it to FAT 32, it work a couple times on my several MAxtor, and Western Digital HD. But this is the last resort and if you are not handy and familiar, don't do it.
It happen on my external HD, so I crack the enclosure open, pulled the HD out and attached it as internal HD on a PC after adjusting the jumper to master and make sure no other HD attached to the motherboard. Make sure the motherboard detected (you can see it from bios menu).
Insert a bootable installer disk before XP ('98, ME, or 2000), and start from there until a promt comes, and type fdisk and you delete the old partition and create a new partition and restart once using the disk still and format it using FAT 32.
After that you put it back to the enclosure, and mount it to MacBook as a new HD with default factory format.
If you don't have the installer disk, this might help :
http://www.bootdisk.com/
But if your maxtor still under warranty better talk to them first and they might willing to reformat it for you.
Hope this help your external back and let you use it on your MacBook.

External Hard Drive suddenly not recognized

I have a WD 500GB external hard drive that I use to back up my data. I only have one hard drive as I'm currently living abroad and couldn't bring a 2nd with me.
I plugged in my external last night to back up my MacBook Pro and it backed everything up. I even went into Time Machine to go back and restore a file or two and that worked without problem. I have been using this drive for about a year to back up everything on my Mac and, although sensitive, it seems to work okay.
I plugged it in this morning and nothing. My Mac will not recognize that the drive is not plugged in in Time Machine or in Finder. If I go to Apple Logo > About This Mac > More Info... > Storage tab, it just shows my internal hard drive and my CD/DVD drive. If I click on Disk Utility with the drive plugged in, it shows my Hard Drive (Macintosh HD) with two icons, one inset below the other and both in black font, and then my external hard drive has two underneath, but only the top one is black font - the one underneath is greyed out.
It goes like this:
250.06 GB Hitachi...
     Macintosh HD
500.08 GB WD My Passport
     Time Machine Backups (greyed out)
Superdrive (greyed out)
When I clicked on the 500GB one and told it to repair/verify it said the disk was working fine. I tried unplugging and replugging in the drive (it is not recognized in Finder so I could not properly eject the disk). I restarted my Mac with it unplugged and plugged it in afterward and nothing.
The HD itself is working, the light is blinking (not solid) and I can feel the hard drive spinning, but I'm at a loss as to what to do to get my Mac to recognize it again.
Any suggestions would be helpful.
Thank you!

I also wanted to add, when I click on the greyed out Time Machine hard drive that's listed and then click "Info", this is what it says:

IPhone 4s not recognized by MacBook Pro nor iTunes

I am currently running iOS 6.0.1 on my iPhone 4s and OS X 10.9.4 on my MacBook Pro Retina Late 2012. I recently reformatted my computer by means of a bootable OSX installer and I did a completely clean install. For some reason, my iPhone is able to charge, but not recognized by my computer nor iTunes at all. Nothing comes up.
I have followed the directions in the following:
http://support.apple.com/kb/TS1591?viewlocale=en_US
and
https://discussions.apple.com/message/24169239#24169239#24169239
Neither solution seems to be working. I have done the following:
reinstalled my iTunes multiple times
reset my networking on my iPhone a few times
restarted my computer
updated all my software
checked to make sure USB cables work
tried multiple iPhone charging cables
I'd greatly appreciate some guidance in regards to this. Thanks!

When you say a bootable OS X installer where did you get the installer? Is it one you created yourself?
You might want to try restarting the MacBook Air holding the Command and R keys. From Utilities on the menu bar, choose Install Mac OS X. That will reinstall using an installer from Apple. Install and see if that changes the behavior.
I did the following from this website:
http://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install -drive.html
Option 1: Use createinstallmedia
Hidden inside the Mavericks installer is a Unix program calledcreateinstallmedia, provided by Apple for creating a bootable Mavericks installer. If you’re comfortable using Terminal, it’s a relatively simple tool to use. The program assumes your account has administrator privileges.
Note: This method does not work in Snow Leopard. It works only in Lion, Mountain Lion, or Mavericks. (The resulting installer drive will let you install Mavericks over Snow Leopard, but you can’t create the installer drive while booted into Snow Leopard.) If you need to create a Mavericks install drive while booted into Snow Leopard, you should use the Disk Utility instructions, below.
Download the Mavericks installer from the Mac App Store and make sure it’s in your main Applications folder. (This means that if you followed my advice to move the installer out of your Applications folder, you’ll have to move it back, at least temporarily. The Terminal command I’m using here assumes the installer is in its default location.)
Connect to your Mac a properly formatted 8GB (or larger) drive. Rename the drive to Untitled. (The Terminal command used here assumes the drive is named Untitled.)
Select the text of this Terminal command and copy it:sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Launch Terminal (in /Applications/Utilities).
Paste the copied command into Terminal and press Return. Warning: This step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data.
Enter your admin-level account password when prompted.
The Terminal window displays the progress of the process, in a very Terminal sort of way, by displaying a textual representation of a progress bar: Erasing Disk: 0%... 10%...20%... and so on. The program then tells you it’s copying the installer files, making the disk bootable, and copying boot files. Wait until you see the text Copy Complete. Done. (see the screenshot below), which could take as long as 20 or 30 minutes, depending on how fast your Mac can copy data to your destination drive.
You now have a bootable Mavericks-install drive.

USB flash drive not recognized on desktop or disk utility

I see a number of similar threads to this but nothing solves this problem. Any help will be greatly appreciated as I am about to go crazy!
I have 3 USB thumb drives that all worked 2 days ago - now only one does. I have tried all drives in multiple ports and the same result. I have restarted the iMac (2009 Yosemite) a number of times and the same result.
This came about attempting to create bootable USBs with each of these. I was struggling with the process on my mac so took 2 (brand new 16GB PNYs) to a PC created the live boot USBs and they booted fine on the PC (knowing this wouldn't boot my mac). I did however plug them into my mac and they were recognized. I finally found success creating a Ubuntu live boot with my old USB. With that success I wanted to try with one of the new USBs on the mac.
Here is what I did:
1. Using Disk Utility - Reformatted the drive 1 partition MS Dos FAT 32
2. In Terminal unmounted the drive and ran a dd command to copy the linux .img file successfully
3. Box came up saying drive not recognized and selected to ignore (this happened on my old one that still works also)
4. Ejected drive from terminal
5 Restarted mac and attempted to boot from USB without success.
After this the 2 new USBs were no longer recognized in any usb port while the other still is. They do not show on the desktop nor in Disk Utility. I checked them on the PC and they are still both recognized and showing the FAT 32 format.
Help please!

Thank you for the reply. I found some time to go through this process a number of times without success
Any other suggestions?

802.11ac not recognized on Windows 8.1 Pro under Boot Camp.

I just installed Windows 8.1 Pro under Boot Camp. The issue I am having is that the 802.11ac network is not recognized in Windows. Windows only recohnizes the 802.11n network. When I boot up OSX Yosemite, It works as usual. Anyone else have this problem?

8/8.1 will install fine but there's some stuff you need to do before starting to ensure no issues
purchase a retail 8/8.1 license
use only a USB2 flash drive
get a clean 8 or 8.1 ISO
newer machines are more selective with the ISO for some reason (ISOs that worked to install Windows on many different older Macs would not work)
if you've made lots of changes, hacks and adjustments trying to get this work on your own, you should clean install OSX first, do not restore from time machine and start at step 3 to get Windows installed, you can go back later and copy files back to OSX
if you want to try without clean installing OSX, here goes
open boot camp assistant (bca) and choose option 3 ONLY if it reads 'remove/delete' Windows
open disk utility (du) and confirm that your HD now only has 1 single partition ('macintosh HD' unless you've renamed it)
restart machine and do a PRAM reset
open du and repair permissions TWICE
open bca and choose all 3 options (create, download, install)
from here, the process follows the standard boot camp instructions (http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf) but pay attention to step 3 where you do have to manually reformat the boot camp partition
clean ISOs

[CLOSED] CD/DVDs not recognized (hal-less KDE)

Hello everyone,
after the last system upgrade last week CDs and DVDs are not recognized when I insert them in the drive.
I'm running hal-less KDE 4.6 with udisks installed.
I removed hal after the upgrade, however the drive could not recognize the disks even when hal was running.
I searched the forum but haven't found any discussion reporting the very same problem.
Can anyone help me to debug this?
Thanks!

I had the same / similar problem. Just that given that I build my own kernel I thought this was what was causing it. That's why I rebuilded the kernel and enabled ISO and UDF modules in Filesystems. If you're using the standard kernel I have no idea what could be the problem.
