EXTREME lag after installing Windows 8.1 pro via / Bootcamp assistant

Hey guys, today I've literally been through **** trying to get this game working on my MacBook Pro.
I've basically gone out & bought Windows 8, created a partition on my hardrive (of my MacBook Pro) & installed it into that partition using Apples 'Bootcamp assistant'. After installing the operating system I also loaded the drivers which were given to me by Apples 'Bootcamp assistant'.
I now have the game on the Windows 8 (on my MacBook) which is a £2000 machine... I have got to the menu & experienced extreme lag to the point where I've even managed to turn down all my video settings & it is still lagging a lot despite my high-end computer hardware - here is my computer http://store.apple.c...B/A&step=config#
I have tried running the game on this website http://www.systemrequirementslab.com & everything is great but it says I don't have the required 512MB of video RAM... It says I have 256MB. This is complete ********? I believe I have 2GB of GDDR5 video RAM. It also says that my graphics card is called 'Microsoft Basic Display Adapter'. So I believe this is where the issue lies. My theory is for some reason one of the drivers which I have installed which was given to me by the Bootcamp assistant is messing with me.
This is literally all the information I can possibly provide, does anybody know how I could fix this?
Thanks you!

If the underlying hardware was exposed correctly by the CSM-BIOS when Windows was installed, your Device Manager should look like this.
If the Windows installer did not see any devices as your screen indicates, Windows will use generic software-based drivers which will be very slow and painful.
Rudegar ... I think the Windows installer did not see any hardware, otherwise there should be HW with yellow triangles with exclamation marks.

There is no need for anyone to use 32-bit version anymore.
Retail comes with both. Or you can save on just buying 64-bit System Builder disc.
Better support for today's hardware with larger video graphic memory and systems.
Better memory management.

Can't install Windows 8.1 because the Bootcamp Assistant-partitioned disk is GBT and not MBR.

I can’t install Windows 8.1 because the Bootcamp Assistant-partitioned disk is GBT and not MBR, and attempting to format the bootcamp disk does nothing. I have read up on this issue, and the only solution seems to be to make a backup of my computer and reformat all disks via 8.1 setup terminal. I REALLY do not want to do that, is there any way to fix this? I’m on OS X Yosemite, if that pertains to the thread.

Interesting. It wouldn’t install because I had FileVault enabled. Huh. Disabling it saved the day.

Installing Windows on Macbook Pro, NO BOOTCAMP

I have a 15 inch core 2 duo Macbook Pro and I went to restore my computer to tiger once again and when I did I relised that the disk is too scratched up, I can only get about 90 percent of the minimal installation done.
After a while of trying diffrent things i got fet up and partitioned my hard drive to Master boot record and poped in my Win7 install disk, I installed Windows 7 perfectly with no problems but now when I go to boot it up all I get is a grey screen and after a while a folder icon pops up with a question mark on it.
How can I fix this without using another mac or bootcamp, because I DON'T have access to one and i DON'T have access to another mac cd, so don't give me that option, lol.. The only thing I have access to is another windows 7 computer.
Please help, I thought mac was suppose to be one of the top brand computers. especially with the price of them, but so far I've had more trouble with this mac than what I did with my HP, I had my HP 3 years now and my macbook not even a year.
Thanks,

Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the desired disk icon from which you want to boot.
5. Click on the arrow button below the icon.
Select the Windows disk icon and click on the arrow button.
Where did you get the Windows installer from? Your HP? That's an OEM disc that cannot be used except on your HP. You need a retail Windows disc if you want to boot the Mac exclusively with Windows. Of course you will not have any of the hardware drivers for Windows for use on the Mac hardware.
I don't understand your complaints about a computer you don't seem to know how to use, your installer discs are all scratched up and no longer usable, but you have had lots of trouble with it. And, all your doing is trying to use it as a Windows computer. Defies logic.

How to Install Windows 8.1 Pro with Bootcamp

I have an early 2011 MBP 15" that's running Mavericks, and I just got Windows 8.1 Pro with an install disc. I'd like to install W8 with Bootcamp, but I can't seem to find any guides on doing this, as most people have retina MBPs which have no optical drive (bad design choice, IMO), so they utilize a flash drive. How would I go about doing this properly?

Welcome to Apple Support Communities
With a disc it's much easier to install Windows 8.1 on your MacBook, because the steps are the same as for any other Windows version.
Boot Camp Assistant (in /Applications/Utilities) will guide you through the first steps. Then, follow Apple's steps to install Windows 8.1 > http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf

Installing windows on macbook pro without bootcamp. Will this allow for switchable graphics?

Hi everyone, I was thinking of buying a new Macbook Pro Retina 15 Inch with the discrete nvidia graphics card inbuilt with it.
I love windows and I am planning on running windows 7/8 on the macbook pro as my primary OS (because of advantages of gaming and being familarized with windows os), however I have heard the issue of running windows on bootcamp severally drains battery life as apple does not allow you to switch the nvidia graphics to the integrated graphics. Is this true? I have heard that running windows 7/8 on bootcamp allows for only around 3:30 hours of battery life, whilst OSX allows for 8+ since it uses the integrated graphics primarily when not running GPU demanding applications.
I am wondering if you can install windows 7 without bootcamp which will wipe apple OS from the laptop completely. Will this allow for the laptop to do switable graphics without problems allowing the laptop to save much needed battery life?
Thanks in advance.
Michael

Sorry it seems to have taken so long for you to get an answer on this question!
Your last post was mostly right... It IS a bad idea to go that route!
While it's technically POSSIBLE to get Windows in place without OSX, it's a MAJOR technical hassle and you need to jump through several hoops to get to that point.
In addition to the hassle required, having an OSX partition can be incredibly useful at times - I've had my Windows system break several times in the past where the automated (and even manual) startup-repair process failed to get Windows booting again, but a short boot into OSX later, I have the problem resolved (via OSX) and am able to get back into Windows.
Finally, you need to be aware that the graphics card situation isn't because of the presence of OSX. Just because you get rid of MacOS doesn't mean you suddenly will be able to use either graphics card! The limitation comes into play with the hardware drivers necessary to get all your hardware working in Windows - they just don't have the facility to switch graphics cards built into them.
I'm afraid you're stuck with the NVidia card when using Windows, one way or another!
Bootcamp is a prerequisite BTW. Without it you won't be able to get Windows installed at all (at least not without MAJOR stumbling block, again!), and again, the graphics card limitation isn't due to OSX or Bootcamp.
Also, battery life... Yes. You'll have significantly less in Windows, and this isn't entirely because of the graphics card situation either. MacOS is just built so well, with the limited hardware used by Apple in mind, that power-management when using OSX os significantly better! The legendary battery life of Apple systems is actually primarily due to the operating system, not the batteries themselves!
As a helpful indication: On my 2009 17" MBP I get about 7 hours on the integrated chip in OSX (8 is pusing it, but is possible sometimes); about 5 hours in OSX when using the NVidia; and about 3 and a half when I'm in Windows.
Hope this all helps you. If you have any further questions feel free!
Apologies for the scattered approach to answering your posts - it's LATE where I am and I"m kinda rushing through things... :-)

Gaming issues and heat issues, running windows 8.1 pro via bootcamp

I have a few problems, and I don't know what else to do, then to write for help here..
I really hope someone out there can help me, because I have had this problem since I bought my laptop mid 2012, and I got smarter since then, so now I know that I actually shouldn't have these problems, it's not because my very expensive laptop is bad, or that it is a laptop or because it's a mac, regardless of what people say, I'm positively certain that it's a problem which shouldn't be there.
I have pretty great specs, (trust me i checked them out, not the best in the world, but pretty good) yet I can't enjoy 1 single mmorpg game like, Tera, or the new Archeage (currently in open beta), or any other game, (swordsman online)... Even though people say Tera has bad coding, I have tried adjusting things for weeks if not months, NOTHING helps, i get a frame rate that is from 0-25 very unstable, usually around 7-12, and sure if I go the lowest settings in the games I can get very unstable framerates but i guess they can get up to around 35-72 but drops to like 7 or 3 sometimes as well, so even on the LOWEST settings in the games I can't enjoy the games fully... It lags and such because of the low fps ofc...
Other than that it also have a heat issue, mostly when running windows 8.1 in bootcamp.
It get's quite hot, just by opening a browser window, and yes i have tried reseting smc, and p-rams, many times.. nothing seems to help.
And even if it helped the heat problem, the gaming problem is still there.
Now to my specs: (I have the macbook pro retina, mid 2012, 15 inch)
- Prosseser: 2.6GHz quad-core Intel Core i7 processor (Turbo Boost up to 3.6GHz) with 6MB shared L3 cache. "Core i7" processor (3720QM)
- Memory: 16GB 1600MHz DDR3L onboard memory
- Storage: 256GB ssd flash storage. (Seperated into os x = 130GB, windows 8.1 pro = 120GB) Running games and such from my 1TB external harddisk.
- Graphics and video support:
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors.
And here's a link to see what is inside it for yourself: http://http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core- i7-2.6-15-mid-2012-retina-display-specs.html
When that is said, apple's warranty has run out, and I didn't buy apple care, but I still have warranty from the store (humac) I bought it in, because in my country the law is warranty 2 years, no matter what, but if i can avoid it, I REALLY would like to avoid switching it out with a new one, since there could be problems all over again, and I would lose what I have on it right now, plus it's a hassle to get a new one, they will always try and fix it for a long long time before they give a new one, and probably can't find the problem...
But if that's the only thing i can do about it, I will ofc, but just don't advise me to do that, unless there's no other solution to the problems.
Please help me.
ps: sorry if I posted it the wrong place, I wasn't allowed to post it the right place by apple...

Installing Windows 7 on Lion via Bootcamp, problems.

Hello there,
After a while i finally decided to install Windows7 on a partition on my Macbook Pro.
I updated SL to Lion, dowloaded the Windows support software and putted it on a Extrenal HD.
But i have a problem: i don't have Windows7 on a CD, since Windows is often pre-installed on PC's these days.
Which means i don't have Windows7 on a CD, but i do have a legal product key for Windows7 (Found at sticker at the bottom of your PC).
So before i start the Bootcamp procedure i want to ask this:
If i download Windows7 from the internet, and put it on a CD.
And then use that CD to install windows, and when bootcamp asks for the product Key, i just use the one at the bottom of my PC.
Will it then work?
I don't know if the ProductKey is unique, if so, i have a bigger problem.
Thanks for your time and help,
Finn.

Apple Wireless Keyboard is lagging and disconnecting when using Macbook Pro via Bootcamp

Hey guys,
I am using my Macbook Pro (I think from 2009) with an external monitor and the apple wireless keyboard (connection via Bluetooth).
First when I set up Bootcamp everything worked fine. But now suddenly the keyboard is lagging (letters sometimes appear after a few seconds or get stuck and typed 20 times or something) and randomly completely disconnecting.
I already downloaded the newest drivers for Boot Camp 64bit from the apple website, but this didnt solve my problem.
I tried disconnecting the keyboard on mac and then reconnecting on the Windows 7 partition again. Also didn't work.
Of course I had to reconnect the keyboard when on the mac.
But it's not that it's not working. I'm using the keyboard via Bootcamp right now. It's just that it's randomly doing this...
Now I don't know what to do. Do some of you have the same issues or have any ideas that might help?

I am trying to install windows on my mac via bootcamp, and it says I need to download Windows Support Software. I tried, but it says "Download can not continue. The Windows Support Software is not available.

I am running OSX 10.6.8 Snow lepard I am trying to install windows on my intel imac 20in late 2006 via bootcamp, and it says I need to download Windows Support Software. I tried, but it says "Download can not continue. The Windows Support Software is not available. I bought the Imac secend hand and did not get the install dvd's with it What can I do?

You don't need to download the Windows support software, because in Snow Leopard, they are only available as a download for the Late 2010 MacBook Air.
Instead, you have to buy Mac OS X Snow Leopard. The Snow Leopard disc contains the Windows drivers for your Mac, so you have to install them after finishing the Windows installation

Cannot install Windows 7 on Mavericks via BootCamp

I have the USB drive in and an ISO of Win7. It starts the installation fine, but when it gets to the question of which partition to install it on, there are 4 partitions, the first three are a few hundred megs each and the last one is my main 256 GB partition. However, none of the partitions allow Windows to be installed on them. I even formatted the 256GB partion to NTFS, still no luck. I then deleted and recreated the partition in Windows, still the same issue, can't be installed. What to do? This is on a MacBookPro Retina.

Find the one "Bootcamp" that BCA created. It will be FAT32. Use the Advanced Options in the Windows install step to format it. You did that, then something else going on.
If that is what you did then you have some other drives connected that are GUID more likely.
Both are in the install pdf and tech articles. I liked the old support product pages check

Do I need to install boot camp on Windows 7 as well as on Lion? I already installed it some years ago on Leopard when installing Windows Vista on my Macbook Pro. But now after installing Windows 7, many things in windows doesn't work (sound etc.). I made a clean installation because I needed to go from 32 bit to 64 bit.

After installing windows 7 on my macbook pro, i cannot access my mac

After installing windows 7 on my macbook pro late 2011, when I try to access the mac side of the computer it just stays in "thinking" mode and will not open up the mac. Windows side opens and works ok.
I only know enough to try to uninstall windows 7 then hopefully open the mac and possibly reinstall the windows 7.
PROBLEM: I only know how to uninstall windows 7 from the mac side (in the bootcamp) BUT cannot access it??
Any help. Thank you
<Edited By Host>

Hi craig1045,
It is possible that the file system for the volume containing the Mac operating system, or the OS itself has become damaged. I suggest that you follow the steps in this article to try to repair them -
A flashing question mark or globe appears when you start your Mac
http://support.apple.com/kb/TS1440
Specifically -
If your installation of OS X needs repair
If you don't see your startup disk displayed in Startup Manager, or if you see a prohibitory symbol (⊘) appear, your startup drive may need directory repair, or OS X may need to be reinstalled.
If you only see a disk named "Recovery HD" in Startup Manager, select it instead. You can also start from OS X Recovery by holding down Command and R on the keyboard at startup.
From the Utilities menu, choose Disk Utility.
In the Disk Utility window that appears, select your startup disk (usually named "Macintosh HD") from the left side of the Disk Utility window.
Click the First Aid tab.
Click Repair Disk to verify and repair any issues with your OS X startup disk.
After repairing the disk, try to start up normally.
If none of these steps resolve the issue, start from OS X Recovery and reinstall OS X.
Thanks for using Apple Support Communities.
Best,
Brett L
