Bootcamp (Win7)

Heyy guys
I upgraded my MacBook mid-2010 to lion then I need to go into windows (with bootcamp which was setup when I had snow leopard) now windows is giving me this error "Missing operating system" did lion delete windows when I upgraded?? what?? Please help ASAP
Thanks
Guys

Have you tried holding the Option key down after it reboots and see if the Windows option shows up.
Do you have "BootPicker" installed, try here.
Have you tried booting from the Lion "Repair Partition" and "Repair Disk" in Disk Utility?
Have you tried Booting from the Windows disk and "Repair installation" (or whatever it's called)

IOGear KVM + Apple aluminum keyboard + Bootcamp + Win7 - SOLVED

I've read many posts from people who had the same problem I encountered: the Apple aluminum keyboard does not work with the IOGear KVM on a Mac under bootcamp. Everything works perfectly on all other PCs, and everything works perfectly on the mac with bootcamp/win7 using any keyboard other than the apple aluminum keyboard.
The symptoms are that the mac/bootcamp/win7/ combination simply does not seem to recognize the apple aluminum keyboard: the caps lock light does not work and typing seems to do nothing -- although the keyboard still works to toggle the KVM between systems. With some hardware combinations, the keyboard may be temporarlily recognized after a cold start, but the problem always returns with switching between systems. I first noticed this behavior with Win7 and the bootcamp upgrades (in my case, 3.2). In my case the problem occurs with a wired aluminum keyboard, but I think a wireless keyboard would exactly the same.
I have found what I believe is the root cause and the solution.
=========
The cause
=========
The cause is a failure to properly detect the type of machine attached to a KVM port: by default, the KVM auto-detects which kind of machine is attached to each port and auto-switches that port to PC mode, Sun mode, or Mac mode. Usually this works fine, but something in the latest OSX/bootcamp/win7 drivers causes the Mac to appear to the KVM as a PC, so the KVM attempts to present the apple keyboard as if it were a PC keyboard.
I'm guessing that this whole issue might be associated with the new ability for bootcamp to let you switch the behavior of the top row of function keys between apple behavior and PC behavior -- which obviously introduces an emulation layer -- but I could be wrong. If there is anybody who has this same problem without bootcamp installed then it could be a more generic driver issue. Fortunately that doesn't matter, because the solution is the same in either case.
============
The Solution
============
All these IOGear autoswitching KVMs share the same logic, so this method should work for all. The manual for one of the simpler models of IOGear KVM is available at www.iogear.com/support/manual/GCS634U.pdf
The first thing to know is that the manual is incorrect in its description of how to use the numeric keypad to enter hot-key-mode (HKM): the manual says to hold down the "clear" key for 2 seconds, then add the "-" key for one second, then release the minus key and the clear key in quick succession. Unfortunately, this technique rarely works: one second is much too long to hold down the minus key. Instead, hold down the "clear" key for a few seconds, then just tap the "minus" key as quickly as you can, and then release the "clear key." You will see the LED flash on the capslock key, and you are now in HKM mode and can change settings on the KVM. To fix your problem you simply need to execute (HKM) (F2) on the proper port as described below.
First switch your KVM so it shows the screen of the Mac where you are having keyboard recognition problems: the correct port will now be "active" on the KVM. Put the KVM into hotkey mode and press F2 -- this will override the default autodetect setting for this port, and will set it directly to Macintosh mode. Your keyboard will immediately be recogized (and the capslock light will work!). The KVM will remember this until you change it or reset it to its factory configuration.
If you need to troubleshoot you can use another hotkey combination to print out the current settings of the KVM: open a text editor and position the cursor inside it for typing, then execute (HKM)(F4) -- the KVM will "type" its current settings. Here are mine on a 2-port KVM immediately after setting my Mac Mini port
= = = = = = = = = = = = = = = = =
hotkey:
(num lock)+(-) and (ctrl),(ctrl)
os setting:
port1 pc
port2 mac
kb:
port1 english
port2 english
= = = = = = = = = = = = = = = = =
It took me two whole days to research and test and resolve this problem, and I've read many other posts from people who couldn't find a solution & went out and bought new keyboards or different types of KVMs. I hope this posting can help somebody else avoid that difficulty.
Good luck!

Magic Trackpad pairs with Bootcamp (Win7) MBP instead of another MBP w/Yosemite?

I've 2 MBP's - a Yosemite MBP and one running Win7 via Bootcamp. When the Yosemite MBP is off, the Magic Trackpad pairs with the old MBP (Win7/Bootcamp). I see no clear way to disable this pairing in Win7/Bootcamp or a clear way to disable Bluetooth on the Bootcamp/Win7 MBP either. I can shut down the Win7/Bootcamp PC, but this gets old very quick, as I tend to carry my Yosemite MBP w/me at the end of the day.
Any suggestions from the Mac Geniuses? Thank you.
Martin

Based on the multiple issues, I think I would reinstall OS X 10.10 from the recovery disk (your data is untouched). As always though, make a good backup before doing anything (I use Time Machine and I also make a bootable clone).

Bootcamp win7 secondary screen brightness

Hi,
I have a macBook pro with bootcamp (win7-64) and a secondary screen connected trough the hdmi. The brightness of the secondary screen changes constantly, seems related with the content of the same screen. For example, if i have opened a photo, wich is mainly dark, and I maximize a program like Word, which is mainly white, the brightness changes a lot. this problem doesn't happen in laptop screen.
The win7 brightness control seems to affect the laptop screen only.
How to disable this annoying secondary screen brightness auto adjust?
Thanks

This seems like it applies:

Bootcamp: Win7, not enough memory.

I mainly run Bootcamp: Win7 for gaming such as StarTrek Online and it generally runs well. However, often when playing StarTrek Online I get a little message from the computer in the upper right hand corner telling me the game is "running in reduced textures due to low memory." I have 8 GB of memory installed on the MacMini. This is the maximum the mini can hold and should be sufficient. Has anyone experience this problem?

This sounds logical. Do know if the video memory in a MacMini can be adjusted? I have a feeling it can't and I'm at work now so I can't check. Perhaps in the Windows settings I could tweak it? Thanks!
Update: I read up on it... it's a shared system memory thing. So, no way to allocate.

Can not log onto Yahoo Mail on BootCamp Win7. No problem on OSX

I can use latest version of FF to view my Yahoo Mail account on my MacPro with latest version of Snow Leopard but when I switch to my BootCamp Win7 I can not log onto Yahoo Mail. I don't get any error. It just comes back to the Yahoo Mail log on page. Win7 is current and FF is ver 3.6.13

I cannot hear voice through my headset under bootcamp win7.

I cannot hear voice through my headset under bootcamp win7.
would anyone provide update for Mac Air Boot Camp4.0 with Win7 32 bit ?
thanks

There are quite a few posts about the same sound issues so the best thing to do is to do a search here for something like "no sound in headphones in Windows" or something similar and try the one that fits your problem.
Basically you have to enable them in the sound Control Panel, re-install just the Boot Camp sound drivers manually or possibly down load the sound drivers for your hardware (your sound card) from the manufacturer directly.

Why Apple Thunderbolt Display won't work on BootCamp Win7 64-bit while being plugged to MBA?

Hello,
I have MBA (latest) & installed win7 64-bit in BootCamp, I do also have Apple Thunderbolt 27" Display.
When I disconnect the ATD and re-connect it in Mac OS X, it works fine like a charm, but when I disconnect then re-connect in BootCamp, it doesn't work at all whatsoever, in fact, I have to restart my MBA (while thunderbolt is connected) to make it work in BC, this is the only way to make it work.
So, my question is; If I disconnected ATD in BootCamp then re-connected it, why it won't work?
I've googled everywhere about this issue, but no luck.
Any idea?

to calculate how much video ram is needed one
take
the vertical number of pixels and * with horisontal number of pixels and * with 32bit colour which is 4 bytes
so if it's the 13" macbook air
1440 * 900 * 4 = 5.184MB for main display
+
2560 *1440 *4 = 14.75MB for second display
sounds like the intel hd 5000 would have that as dedicated memory even if the windows driver did not allow to use shared system mem as extra
could be a problem with the driver for windows
maybe a person who ran a setup like yours would have more to contribute with
my setup is an imac 21" with amd video card and a 24" dvi dell monitor and that works fine in windows so it's a different animal altogether

Corded Mighty Mouse only middle-clicks in bootcamped Win7

... whereas in OSX, middle click ceased to function.
So let me explain this further:
I have a corded Mighty Mouse, model number: A 1152
In OSX Snow Leopard, it is only capable of left clicking. I don't know why right and middle click won't work (the wheel also only goes up). In System preferences I have set Left and Middle buttons to Left click; right button to right click. But I use ctrl+click because right click won't work. So, I'm pretty much used to this setup although the Mighty Mouse is only a year or two old.
Then I installed Win7 via boot camp. Clicking was weird during installation so I managed to get over it with the keyboard (which works fine btw). But then, after installing all the updates and the windows support software it still only middle clicks. Sometimes, maybe depending on certain pressure angles on the mouse, it will do a normal Left click, but the next click is mostly middle.
So how come middle click doesn't exist while in Snow Leopard but in Win7 there is only middle click?

did you use osx bootcamp to make a windows driver disc ? if not do so

BootCamp - Win7 x64 Ult - No drivers found

Hi all,
i want to install Windows 7 64bit on my new MacBook Pro i7 and i used BootCamp.
BootCamp make succesfully a Driver-USB-Stick and i have a original Win7-64bit-Ultimate-DVD SP2.
Windows 7 Setups boots and its ok, then set language and contiune.
Then comes a error, no disk-drivers found to find a harddisk.
I search all contents of the BootCamp-Driver-Stick, but there is NO driver to found any harddisk or partition.
I boot up my MAC and the harddisk utility found the new parttion for MS-WIN7.
Please help me to find the right correct driver to install Win7 in BootCamp!
Thx
Gerd

Hi,
sry, i mean WIN7 x64 Ultimate SP1.
On setup procedure, Win7 Setup founds normaly my harddisks with partitions.
This field is empty and a error popup comes, i must insert correct driver disk to find harddisks.
WHERE are the drivers to find any harddisks???
In my MBP is only one drive, BootCamp make correct format for Win7, but the Win7-Installer cant find andy harddrive. The setup means i must insert a driver-disk.

Some OSX folders under bootcamp (Win7) not visible - why?

Hello,
a few months ago I set up Win7 via Bootcamp on my MBP 13.3" (mid '09) and I noticed that sometimes (when in Win7) I was searching really long for a specific folder (just a folder with some music in it, nothing special). I gave up and thought I might have accidently deleted it. But when back in OSX I directly found the folder, so he was there. The name folder is named "Ambient/Chillout". But interestingly the problems also exists vice versa. Some Word documents (written under Win7) are not visible for me when in OSX. They are not even visible when I copy the document to an external device (flash usb drive).
Does anyone have an idea what is going here?!
Thanks so far.

Well, somewhere there is/was a question? I guess.
Without the driver from MediaFour or Paragon you can only see some folders, and not be able to see or mount folders, drives and partitions outside the limits of the AppleHFS and home folder or share folder.
So if you want to use an external drive, you can't.
With a driver you don't need to copy back and forth - word and itunes need write access to open those items.
I don't like Spotlight reindexing Windows partition over and over or leaving hidden ".DS and ._DS" files in every folder so I place them in Privacy tab.

Fail to enter bootcamp win7 after replacing CD-Ron with SSD

I replaced CD-Ron with SSD.
I successfully enter mac on both HD and SSD, failed with enter win7 on HD.
It stops at black screen and a write bar shining on the corner.
Is it because the windows system can't find my CD-Ron?Then how?
Tks. ^^

So I try booting without the DVD player attached, and there is no Windows option or startup item.
I try booting with the DVD plugged in, but without the USB attached, and I get the Windows DVD to show as a start up option: I click it and it sits with a black screen and the blinking prompt.
I am seriously at a loss here folks. What the heck.
The machine sees the DVD.
It does not see or acknowledge the USB stick as anything past the BOOTCAMP function of putting files on it, but nothing happens with it past that.
Am I missing something in BootCamp? Am I missing an option?
Cello?

MBA Mid 2012 - Bootcamp Win7: Headset Mic not recognised in Win7

Hi,
I have a MBA 13" (only had it about a week...). I put bootcamp on and Win 7 x64 ultimate. All is working really well except when I plug my headset in, Win 7 only recognised the headphones.
I have tried this in OSX and the mic work, its an Iphone compatible headset, so not only does the mic work but the volume buttons on headset work also. However, when I plug this in when in Win 7, no external Mic is detected.
Any ideas? I've tried reinstalling the Bootcamp audio drivers, no change. Unable to locate any online either...Cirrus Logic CS4206b (AB 86).
I have seen a few of these posts online, but from about 2 years ago... has this been fixed yet?
Thanks

Hi,
Thanks for your reply. The issue is with Windows, but it appears to be due to OSx drivers from bootcamp, that does not detect both input and output from the headphone jack. There are no drivers required, I have used this headset on various other Win7 x64 machines.
As above, it works fine in OSx, it is just that bootcamp drivers for the soundcard do not include that the hardware on my MBA allows both input and output from the same jack. Ms dont supply drivers for Bootcamp.
Thanks.

Rocket Raid 2314 & Bootcamp Win7

I have been trying to get an eSata card to work with my 2009 Mac Pro and its been nothing short of nerve racking.
I tired the Rocket 622 but that would not recognize PM (port multiplier) cases or boot to Windows 7. Highpoint assured me that they would upgrade the drivers but I can't wait. NewEgg has a 30 return policy. So I did some research and it looked like the RR2314 would work. I returned the 622 and ordered the 2314.
Out of the box it Kernel Panicked allot. I installed the drivers from the website and it stabilized in 10.6.2. All seemed good, until I tried to boot into Windows 7.
I hold option when booting, select Win7 partition (internal drive not on esata!), screen goes black, and nothing.
If anyone has any idea how to fix this please let me know. I am really tired of throwing money to get some type of eSata backup system and seeing it fail. (This has become like a 6 month nightmare. I got stuck with a bad case, etc...)
I have 11 more days to RMA this with NewEgg. I would rather see it work.

1. I updated using my aunts computer which I had because I was cleaning it up. It happened to have a PCIe slot. I updated the drivers and disabled all the fancy boot options but that did not work.
2.I do not recall a boot screen from the card. Weird. The computer booted normally while the card was installed. (To WinXP)
3. My original partitioning was: Apple Provided 650GB HD split to 500GM jHFS+ and 150GB NTFS. Windows XP CD would not boot while the card was installed. I didn't bother trying the Win7 CD. I have had absolutely NO problems with bootcamp when there is no eSATA card installed. The installs must be ok. I have installed XP, Vista, and later Win7 on this Mac Pro. All worked flawlessly this past year. I have booted many times into Win7 prior to installing the card. I did consider something funky with the boot sectors. I moved all my data off one of my 1.5TB internal volumes, reformatted, moved my OSX boot volume there via CCC, partitioned and formatted the 650GB internal as NTFS and gave Win7 the entire drive.
Something else is amiss here. I have checked the computer up and down and I seriously doubt there is an issue with the computer. I ended up sending the RR2314 back. My time for RMA was running out. I am thinking about getting the RR eSATA as that runs EFI and should (theoretically) be ignored by Win7 at boot. The only problem I have is that I am out $70 so far with restocking fees and shipping back to newegg. I am abit hesitant to order the RR eSATA because of this. It will cost me another $30 if it doesn't work. And there is no guarantee that it will be supported come 10.7.
Thank you for taking the time to help me. I really appreciate it. You gave me quite a few avenues to try when I though I had run out of ideas. The one thing I didn't try and I regret not finding this out till after I sent the card back was that the RR2314 and RReSATA both share the same chipset. There is a possibility that the RR2314 could be flashed with the RReSATA EFI. Again I didn't try this as I just found out last night after I returned the card.
I will keep this thread open in case I decide to try the RReSATA card. If I can help someone else and possibly save them money it would have made this nightmare worth it.
For anyone out there that does not need bootcamp support the Sii3132 card that comes with the TR4M
http://bit.ly/6k4jIg works beautifully with the Sonnet drivers found here http://bit.ly/3A8jJK
The drivers show you all the drives in the case but do not provide any type of RAID. For a cheap solution that works this is it. If however you try to boot into another OS it will not work. Also you will not have boot support to OSX from a drive connected to the eSATA. You will also not have access to your data if you need to boot from the OSX install DVD. (Unless you hack the DVD, which is not all that hard. Or install 10.6 to a USB drive and install the drivers to that.)

Lion bootcamp win7 freeze during install

Hi,
Been looking all around and cant find a resolution.

Then started windoes install of win7 ultimate 32bit.
The last step after the first reboot it freezes at completing installation. I let it sit all night and in the morning, its still sitting there.
I re-tried 4 times now and still doing the same. I also tried with another win7 enterprise and did the same.
Why is this not working? Im doing all as stated in the docs

Can anyone tell me why this is not working?
Has anyone been able to bootcamp with windows 7 on osx lion?
Please i need your help

Bootcamp Win7 failure

Hello, I have an iMac late 2011 21.5 inch, I have Windows 7 Ultimate bootcamped on here and I get a complete shut off/failure while using it. I've had to get my iMac fixed 4 times now, because of this, some kinda of hardware problem of some kind. And it keeps happening.

I also have a late 2011 iMac that had the 1TB defective drive. I have a Win7 Ultimate partition as well but I do not play games on it. I use it for certain programs that I desperately need that are not available for iMacs. However, they replaced the seagate drive with another seagate drive and I am still having problems with it. I have run the disk utility on the Mac portion of the drive and it tells me it's fine. In the past I used to fix all types of computers myself and everytime there was a seagate drive there were problems of disk failure. My iMac is in a location where it has plenty of ventilation. I do turn it off daily to cool it down as well. Therefore, heat should not be a problem. Check to see what brand of drive you have....that could be your problem.
