How to Install Windows 8.1 Preview on a Lenovo B575

First off, if you try to do it the normal way (eg, download ISO and burn to DVD) it will fail miserably and you will end up with an installation that hangs during a shutdown and/or restart plus some features may not work (like your wireless perhaps) so here's how to get it to work by doing a USB Legacy installation workaround:
1- Download the Win 8.1 ISO and use a utility like ISO to USB to make it bootable via a USB stick.
2- Once installed on the USB stick, delete the EFI folder and the efibootmgr file (on the new USB stick).
Note: This will force a Legacy USB installation - see image for more info.
3- Complete the installation using the modified USB stick and you will end up with a correct Legacy installation.
Note: It is very important to delete all existing partitions as part of the "clean install" process.
Note: See image of Disk Management below.
Now, there is only one problem left to solve and that is how to create a backup system image because this feature has been removed in 8.1 and doesn't work in Win 8.0 (with a B575) so what to do? The simple alternative is to use a free 3rd party utility like Macrium Reflect Free to create and restore your system images as required. BTW, 8.1 seems to be working nicely but I would not recommend upgrading your primary PC/laptop to take it for a test drive. In my case, I have a test rig for those purposes. Good luck.
BTW, see my tale of woe on installing Win 8.0 (similar to here):

Moderator Note; subject edited. Windows 8.1 is not yet a supported operating system, members installing it do so at their own risk.

Here is a screenshot of the 8.1 Preview on the B575 (desktop view):

Here is Macrium Reflect Free preparing for a system image backup:

Now, if you are so inclined to attempt this installation, I would strongly recommend the follow recovery actions:
1-Download Macrium Reflect Free and make a System Image Backup for recovery to Win 7
2-Install Win 8.1 as previously described.
Also note that I have installed the new Classic Shell Beta that works nicely with the return of the Win start button.
Please understand that all information provided is not an encouragement to attempt an installation of the 8.1 Preview on your Lenovo B575; however, it is intended to help you get through this installation if you are a curious sort (like me) and it is also intended to avoid issues when attempting this upgrade to your B575 laptop. With that said, I would strongly advise against attempting this upgrade; especially if your laptop is considered a primary computer. The only reason I can do this without fear of consequences is that I use my B575 as a "test rig" to assist others with complexed situations so I am "routinely" switching back and forth between Win 7, Win 8.0, and Win 8.1 as needed. So, take heed and good luck with any decisions you may make.

Hi bitofagiggle,
I am not familiar with mac machines, based on what I know, there should be more settigns that need to be configured before the installation of Windows, I suggest you contact the manufacturer for further help regarding how to make Windows to upgrade smoothly.

How to install Windows 7/Vista as 2nd OS and retain predesktop environment (service partition)

This is a step-by-step instruction how to install Windows Vista or Windows 7 as a second OS on a Lenovo Thinkpad that originally shipped with Windows XP AND how to retain the access to the Lenovo Service Partition.
I have been searching the internet for instructions like these but could not find anything useful. So I am posting it
here. Maybe this helps other users.
I have tested the procedure below with installation of Windows Vista Ultimate (64bit) and Windows 7 Ultimate (64bit). I believe that the procedure will also work with the 32bit versions of these OSs. I am not totally convinced that this works when the OS to install is Windows XP (64bit or 32bit). XP has a completely different boot sequence compared to Vista or 7. The basic steps would remain the same, but the XP setup is less forgiving when it finds an unknown partition. If somebody wants to try it out, please post your results as a reply to this forum entry.
Never never never try to install an older OS (like Windows 2000 or NT) as a second OS when XP is already installed! This is doomed to fail.
The procedure below does NOT work for Linux installations. I am not a Linux wizard, but any Linux bootmanager I know about is incompatible with the Lenovo Service Partition.
The procedure was tested on a Thinkpad R61 model 8918-B9G. It should work similar on other models.
You definitely need a service partition with Rescue&Recovery version 4. It will NOT work with older versions of R&R or if the service partition is not a type12 partition (see below how to find out about that).
I assume that the harddisk partitions are unmodified, i.e. still have factory settings. This is likely the case if you
never attempted any OS install or recovery action. If this is not the case, the procedure may or may not work.
You also need a bootable CD with a tool that can change the size of your current system partition. I was using gparted live version 0.5.2-9. ( http://gparted.sourceforge.net/ )
Everything you do is at your own risk. I am in no way related to Lenovo, other than being a customer using their
products.
Step 1) Make a full backup of your harddisk. Get yourself recovery CDs for your Thinkpad model if you don't have any. The changes we are about to make can completely screw up your harddrive. A typo is sufficient for that to happen.
Step 2) Power on the system. Check that you can boot into the Service Partition by pressing the Thinkvantage button when the startup screen appears. (Older systems may have a differently named button.) If there is a problem booting the service partition now, it is likely that the rest of this procedure will not fix it.
Step 3) From the service partition choose 'Warmstart' to reboot the system. Reboot Windows XP, logon.
Open a command prompt. CD to the following directory:
\Program Files\Common Files\Lenovo\BMGR
On a german language system (like mine) it is
\Programme\Gemeinsame Dateien\Lenovo\BMGR
If you have an older IBM system the directory may be named
\Program Files\Common Files\IBM\BMGR
or something like that. Maybe you need to search around.
In the following, I will call this the "BMGR dir".
Enter the following command:
bmgr32 /info /v
You should get an output similar to this:
C:\Programme\Gemeinsame Dateien\Lenovo\BMGR>bmgr32 /info /v

The important thing to look for is the 0x12 partition type in the partition table at the bottom. This is the service
partition. If you do not have a 0x12 partition, then you can stop here because the rest of the procedure will not work
for you.
Step 4) Shutdown and boot gparted from CD. Shrink the system partition to the desired size. Do NOT touch the service partition! Do NOT attempt to create another partition! Leave the new white space on the disk untouched! Apply changes and restart the system.
Step 5) Reboot XP. gparted has set the NTFS dirty bit. This will cause XP to run a full CHKDSK. Depending on how much files there are on the partition this may take considerable time. Let CHKDSK run to completion. When CHKDSK finishes, the system will automatically reboot.
Step 6) XP reboots now. Logon. When loading the desktop, XP will show a popup window, stating that system settings have been changed and new devices been discovered and that the system should be rebooted. This is ok. XP actually recognized the shrunk system partition and applied the necessary changes to its own system parameters. Click YES to reboot the system.
Step 7) XP reboots. Logon. Open a command prompt, CD to the BMGR dir and enter:
bmgr32 /info /v
The output you get should be similar to the output you have seen in step 3, except that the partition 0 size column
shows a smaller value.
Step 8) Shutdown, restart. Check that you can still access the service partition by pressing the blue Thinkvantage button when the system startup screen appears.
Step 9) From the predesktop environment choose warmstart. Reboot XP. Logon, logoff, shutdown.
DO NOT SKIP THIS STEP!!! If you start the Windows Vista/7 install right after shutting down from the predesktop
environment, the Win Vista/7 setup program will screw up your harddisk! The Lenovo MBR bootmgr reboot takes two steps for completion. The first step is the shutdown and the second step is executed when booting from harddisk. A boot from the Windows CD will skip this second step and disaster finds its way...
Step 10) Insert the Windows Vista/7 DVD and boot it. Start the setup. Choose "Custom (advanced)" install. It will show the partitions on the disk. Select the white space (unallocated). Click on "disk options (advanced)". Click on "New" to create a new partition in the white space. Keep the default size, click "Apply". Click "Format". A popup window appears stating that the partition may hold OEM data. Continue. Click "Next". Installation starts.
Continued in the second post...

Step 11) Win Vista/XP will reboot several times during installation. You will always see the Windows bootmanager with an entry for "Earlier Windows version" and "Windows Vista/7". DO NOT DARE to touch the blue Thinkvantage button on any reboot or press any function keys!
Step 12) When the installation is finished, check that you can successfully reboot Win Vista/7 by selecting it from the Windows bootmanager.
Step 13) Reboot XP by choosing "Earlier Windows version" from the Windows bootmanager. Open a command prompt. CD to the BMGR dir. Enter the following command:
bmgr32 /info /v
The output will now look like this:
C:\Programme\Gemeinsame Dateien\Lenovo\BMGR>bmgr32 /info /v

startLBA and size will of course differ, depending on the actual partition sizes you have set. Note that Windows setup moved the service partition to entry 2 of the partition table. If you do not see the 0x12 partition then stop here.
Otherwise the following step will likely screw up you harddisk.
Enter the following command (case sensitive?):
bmgr32 /Fbootmgr.bin /m0 /IBM /v

So you have actually regained the Lenovo bootmanager. But you are not done yet.
Step 14) Shutdown. Restart the system. DO NOT PRESS THE BLUE THINKVANTAGE BUTTON AT THE SYSTEM STARTUP SCREEN!!! IT DOES NOT WORK YET! When the system startup screen DISAPPEARS, quickly press F11 (maybe several times). The system should now boot the predesktop environment from the service partition.
Step 15) When the predesktop is there, choose "warmstart". When the system startup screen appears, press the blue Thinkvantage button. The system should again boot into the predesktop. The blue Thinkvantage button now works permanently.
Step 16) Check that you can boot Win XP and Win Vista/7 from the Windows bootmanager. You're done!

How to install Windows 8.1 Pro on Macbook Pro

Hello everyone,
I'm new to these forums and new to bootcamping as well but have been reading all kinds of posts about how to install Windows 8.1 on their Macs using bootcamp. I am however having trouble with this situation as I have no clue what to do next. I have a Macbook Pro 2011, running on Maverics, and I recently downloaded a digital copy of Windows 8.1 Pro, 64-bit, for the Mac platform, along with its CD key through my University's hub website as can be seen here.
After finishing the downloading process, I received this file which is about 4GB large.
When i double click on the file this happens. It opens something on DEVICES which gives me what is on the 2nd image.
At this point, I'm at a loss on what to do next. Do i burn the file on a DVD hoping that Bootcamp will recognize it as a windows disc? Any help would be appreciated, thank you.

You need a 'Full' Installer.
From Boot Camp 5.1: Frequently asked questions - Apple Support
Which versions of Windows work with Boot Camp 5.1?
Boot Camp 5.1 supports 64-bit, non-Enterprise versions of Windows 7, Windows 8.0, and Windows 8.1. This version of Boot Camp doesn't support Windows XP, Windows Vista, or any 32-bit version of Windows. Depending on your Mac, you may be able to use an earlier version of Boot Camp to work with other versions of Windows. For details, see the Boot Camp system requirements for Microsoft Windows.
Can I perform an upgrade install from a 32-bit version of Windows to a 64-bit version of Windows?
It's not possible to upgrade a 32-bit version of Windows to a 64-bit version of Windows. Back up your important files, then perform a new install of the 64-bit version of Windows.

How to install Windows 7 on a MacBook Air?

Hi everybody,
I am sorry in case this has been covered before, but i couldnt find anything searching different categgories here, so i´d appreciate some help.
I have got a late 2011 MacBook Air with lots of SSD and so on and i want to install windows 7.
I bought a wndows 7 OEM DVD (actually, two discs, one says support software)
I have tried to run bootcamp and follow the instructions, but to now end.
on my macbook air, i get the option "create a windows 7 disc" or something like that (the first option), which doesnt help me because i dont have optical drive
when i start boot camp on my iMac, this option will be greyed out.
Also, I have tried to to ISO copys of the windows DVD and save them to a USB stick but i just wouldnt come to any result.
does anybody have a good, comprehensive instruction on how to install windows 7 on an MBA withou optical drive?
Also, is 30GB OK for Win 7 if you basically dont wanna do to much in windows (no office etc, just some small clients)
thanks!

30GB is not enough, especially on an SSD. Normally 50-60GB and with SSD I'd go with 80-90GB.
http://www.apple.com/support/bootcamp faq, how to, special instructions for Air
There is a program to create DVD from ISO or .exe
Apple Boot CAmp Assistant should have prompted to save a driver for you to support a USB-DVD, in addition to the normal Apple B.C. drivers you save to flash card.
Disk Utility is not a good method for burning Windows DVDs.

How to install windows 7 on Old Macbook Pro 15'inch 2.3 Core 2 Duo

How to install windows 7 on Old Macbook Pro 15'inch 2.3 Core 2 Duo:
I want to known how to install windows 7 on Old Macbook 15'inch 2.3 Core 2 Duo by using usb
I try many time, but after restart bootcamp partition, apple show blinking folder error
I think this firmware not support to install windows by usb
NOTE:
I Cannot install Apple New OSX Mountain Lion, Mavericks etc in this MAC
If I cannot install windows 7 on this MAC, so tell me what I will do with this MAC ?

I agree with the optical drive, mine acted strange, and i thought people were crazy and my drive was shot, but a simple cleaning disc worked miracles.
But- are you trying to reboot with both the USB install and the DVD install both plugged in? that would definitely cause confusion.
Do this, reboot with NOTHING plugged in. Once you hear the Mac chime, immediately press and hold option.
You should only see the Mac HD, and Recovery Partition.
THEN plug in your external DVD, and wait a min or two, you should see a disc icon appear next to the recovery partition that says something like windows. If that doesnt appear after a min or two, unplug it and put the USB stick and do the same thing. I had to do it this way on my mid 09 MBP.
Let me know if this works to start the install. If not we may have to start over with Bootcamp Assistant

i have windows 8 DVD and i would like to have a clear instructions on how to install windows 8. I dont understand the need for USB

Welcome to the Apple Support Communities
You need a USB drive to install the Windows support software. It contains all the drivers that your MacBook Pro needs, and you will have to install them after finishing the Windows installation. If you don't install them, a lot of things won't work: the wireless card, the sound card, the brightness, the trackpad gestures... Apart from that, you don't need it for anything else.
Apple has released the official steps to install Windows 8 on a Mac, so if you want, print this PDF > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf

How to Install Windows OS on a two partitioned internal HDD?

Hi
I have a late 2011 macbook pro 8,2 (MD318HN/A). A month ago, I installed Windows 7 using Bootcamp. For that I made a partition of 50 GB on my internal 500 GB HDD. After sometime in need of space, i formatted that 50 GB partition using Disk Utility in Mac OS Ext. (J).
Till this everything was fine.
Now I want to install Windows 8 Release Preview :
And now to install Windows 8 Release Preview, when i go to Bootcamp, it shows me an error that windows can be installed on a single partition HDD.
Trying format the internal HDD in one partition:
So i tried format the HDD of my MBP. In Lion Disk Recovery Mode (Cmd+R) using the Disk utility I tried to format the HDD but it gives me an error "Couldn't unmount the disk". I tried many a time but failed then re-installed the Mac OS X Lion from internet. Now that 50GB partition is showing in finder but still the error from Bootcamp exists when tried to install WIN 8.
So tell me what to do?
I have nothing in MBP to backup etc. So tell me any solution. I have arount 4-5Mbps download speed too.
Thank you.

Download MiniTool Partition Wizard. The boot disk is free, and it contains all you need to delete all partitions on your drive. This same problem happened to me when I was tinkering with installing Windows 8 using EFI boot (incidentally, DON'T - Apple's EFI implementation is, to date, not compatible since it's partially proprietary).
The download link is: http://www.partitionwizard.com/partition-wizard-bootable-cd.html
You'll need a USB mouse, since the trackpad mouse wont work with this partiticular image, but it's the easiest tool to use from a user experience point of view, which is why I'm recommending it.
After you delete all partitions using this tool (and press apply) you can go ahead and restore OSX by any means you wish (internet recovery, dvd install etc.)

How to install Windows 8.1 without optical drive

I just got a ZBook 14 which was preinstalled with Windows 7. I want to use Windows 8.1 Pro which was alsp delivered on DVDs in the packages. However, this machine does not come with an optical drive. How can I install Windows 8.1 on this machine?
Thanks

Excuse me for being blunt but that is simply b***hit. Windows 8.1 comes delivered with the machine which is brand new and any reasonably new PC is fully capable of running Windows 8.x. The question was just how I was supposed to load it onto the machine as it lacks an optical drive. I suggest you do not give advice unless you know what you are talking about.
For all others thatwant to the same thing.
1. Make a copy of the Windows 8.1 DVD that comes shipped with the machine. See the following guide http://www.intowindows.com/how-to-install-windows-7vista-from-usb-drive-detailed-100-working-guide/
2. Set Boot mode in BIOS to UEFI instead of legacy BIOS.
3. Boot from the USB stick and install Windows 8.1, wipe all existing partitions. Please note that this will effectively remove any possibility to revert to Windows 7 by using the recovery partition but since Windows 7 DVDs are also delivered you can use the same procedure as above to install that. I guess that boot mode in this case should be set to legacy instead of UEFI.
Of course, you do the above at your own risk but it has worked successfully for me. You could copy the content of the Application and Driver Recovert DVD for Windows 8.1 to a USB stick as well and install that afterwards.

How to install windows 7 on Mac OS 10.9

Hi, all, I recently purchased a Macbook pro 13 with Retina display, it has MacOS 10.9 on board, but I have some work need be done on Windows, so I have to install Windows7, meaning that I will have a dual boot on my Macbook. I did a bit research on how to do that, but either the apple support has article about installing Windows 7 using boot camp, or the community has a unified answer for that. So I wonder how to install Windows 7 on MacOS 10.9, any help is welcome.
cheers

I use Oracle's free VirtualBox with Windows 7 Home Premium. As you might infer from the name, it is a virtualization solution and does not involve storage partitioning as will Boot Camp. It is responsive whether on an older Core 2 Duo with regular drive, or a Core i5 with underlying SSD. A Haswell and SSD solution would make it sing.
I use two large monitors and you can tell VirtualBox to always launch the Windows guest on the second monitor.
Whether you use a virtualization solution or Boot Camp for true dual-boot will depend on what you plan to do with Windows.

Either you will do this correctly or you will not.
You can not have a storage partition in addition to Mac OS and Boot Camp.
I can't help at all if you want to go your own way.
Good luck, backup before you lose data.
