• Old computer is dead, HARD drive still alive. Can I install windows 7 on your new computer without formatting the old HARD drive?

  My old desktop computer recently died of a motherboard failure.  As I understand it, I should be able to install windows 7 from my old computer to the new, but only if I delete the old installation.

  Does this mean that I have to format the old HARD drive?  Because the old computer HARD drive seems to be alive, I would retrieve the data on a new machine first, before I have to format and I need to install windows on the new computer to get the data from the old HARD drive.

  No, it is taken on trust that the old installation is no longer active, there is no mechanism to remove the old license in order to make a valid new. Remove the Windows directory (or rename) makes the old system inoperative.

  You find that the automatic authentication fails on new construction and need to call the licensing Center to check that you have only one installation. Apart from the OEM rules if a license has been activated too often, and recently, it fails in a 1 time.

  Cyber criminals started calling people on the phone, who claims to be from Microsoft and offers help to solve their computer problems. Once criminals have won the trust of the victim, they can do one or more of the following:

  • People thing to install malicious software on their computer.
  • Take control of the victim's computer remotely and adjust settings in order to leave the computer vulnerable.

• Install Windows 8 on external drive Thunderbolt - Windows could not prepare the computer to begin the next phase of installation

  Hi all

  I'm at my wit's end trying to install windows 8. Let me start at the beginning: I used to have windows running on my Mac Pro ssd internal 8.1, installed via bootcamp. It worked well for a while, and then refused to start, gives me a blue screen KERNEL_SECURITY_CHECK_FAILURE. Despite some advice from lonely T, I was unable to fix and ended up wiping the partition and relocation, again via bootcamp. Yet once again, it worked for a few months, then the same problem. I made this one last time, and it only lasted 2 days... So I gave bootcamp.

  I think that the hybrid MBR partition scheme that implements bootcamp is the culprit, but I don't really have evidence to substantiate this claim. In any case, I tried to install windows in EFI mode. (If I understand correctly, the hybrid MBR is set up to allow windows to install in legacy BIOS mode, but that windows 8 may now install efi, which supports my Mac Pro mode.) My Mac is the new Mac Pro (end of 2013, trash in shape), and I can say short UEFI 2.0 (I have the latest efi update from apple installed).

  The method I'm trying:

  1. create a new partition in HFS + on my external drive using disk utility. The drive has now it's efi partition and partition empty 750Go I want to install windows a 1.25 TB storage partition that I use with my mac. It has a GPT. I formatted HFS + and no FAT, because I think that disk utility creates the same hybrid-MBR as training camp every time a FAT partition is created.

  2. use gdisk to confirm that the disc does not have a hybrid-MBR. (sudo/dev/disk1 gdisk watch MBR: protection)

  3 restart my mac and hold the possibility to put in place to bring up the boot efi menu.

  4. Select the EFI_Boot DVD icon (that's the windows 8 install dvd that I have in my superdrive USB drive)

  5. go in the menus of the disk selection screen installation and delete the partition in HFS +, I created to install windows on (the format option is not available)

  6. now select "Unallocated space" on the good drive and click Next.

  The problem:

  Partitioning seems to go ok (there is no feedback on this basis, but it proceeds to the next screen, and all new partitions expected are there if I check diskutil list later). He said it is "copy of windows files", but then stops with the error "Windows has no prepare the computer to start the next phase of the installation." To install Windows, restart the installation. "If I restart, I can start the same process all over again and get the same result.

  The Question:

  How I get this error and get windows install?

  Extra pieces:

  • The first time it happened I assumed it was the new sip / thing "without roots" in El Capitan, causing problems, then I disabled, but I still get the same error.
  • After reviewing the diskutil list output after one of installs it without success, I found that a labeled EFI partition has been created after my storage partition (the original efi partition was still there in the upper part of the disc).
  • I have windows 8.1 installed now bootcamp on my internal ssd. It was planned to use it and winToUSB to put windows on my crush, but I found that it only works with usb2. I do not have installed could cause problems with the installation on another disk.
  • Before say you I can't run windows on an external, yes you can, and many people have. I read windows sees thunderbolt internal disks.
  • I read a few other posts on this and other sites on this problem, but could not find a pertitnant solution to my situation. I found one that suggested to remove the efi on my disk partition, but that seemed like a bad idea, so I didn't try.
  • I write this at 1 in the morning after a day spent in front of the computer trying to get this working, so please excuse typos typing or other. I am pleased to provide you with any pertinant information helping you will help me.
  • Thank you!

  The other thing I tried also almost succeeded:

  Although I prefer to get the method above works, because it seems the most promising, is something else, I've tried that I thought worth mentioning. If you offer advice pertaining to this method rather than the above, I would appreciate it if you could explicitly declare that at the top of your answer. Thank you.
  

  I tried to install windows on the physical disk using vmware and virtual box. The instrutctions I followed for this can be found here: http://www.andrewsavory.com/blog/2011/2156 (the only thing different, it's because it's on an external drive, I created the Fat 32 partition manually using disk utility). The first time (using vmware) installation seems to go off without a hitch, but I couldn't get my computer to see the windows partition as bootable with the boot efi menu hold-option regular refined or with system preferences-> startup disk. I think that I was using always inadvertently a hybrid-MBR at this stage. I tried to repeat this new beginning with the first two steps above to avoid the hybrid-MBR. But now when I try to create the virtual machine based on the gross vmdk, it starts to copy the files then says not sufficient permissions and fails. I don't know if it's a permission with the disk or the hard problem. I tried chmod 777 and chown $USER of the vmdk disk (/ dev/disk1s3) does not.

  Wow, that was a long post...

  1. when a second drive is detected by the Windows Setup program, he wants to create his own brand of EFI (104 MB) and not to mess with the Mac EFI (200 MB). You can force it to use the EFI to the Mac using Diskpart commands.

  2 instead of HFS/FAT32, create a piece of 750 GB free space and it should only get a new MSR/MSD, without the part of EFI.

  3. on your VM method, the link you have is quite old. You have a MP 2013, with references to the 2010 Mac alumni and is a bit too archaic to be useful. http://forums.macrumors.com/threads/install-a-Windows-7-partition-on-Mac-OSX-Wit hout-optical-car-or - usb.1836959 / #post... seems to work for many and can be useful for a test. It also uses Winclone.

  System Restore to go back before the show.

  I suggest you to install the updates one by one and reboot the computer after installing each update to verify that update is causing the problem.

  Also note the updates that you install on the computer.

  Once you come to know what update is causing the problem, let us know.

  Do not install any driver updates offered by Windows Update. Find them in the manufacturer's website instead.

  Try a convenience store
