Multi-partition solution for Macbook Dual System

Multi-partition solution for MACOs: 1. the Mac system is not Intel's i386 architecture and does not have a Bios. However, with EFI, It is guided by the EFI management system. 2. The partition table of the Mac system uses GUID instead of MBR. Therefore, if the hard disk is completely handed over to windows for control, the Mac system may fail to start. 3. Any forced operation on MBR will cause failure of the installed dual-system boot. 4. The Mac EFI partition will be locked with GPT. Do not try to operate the partition. Taking a bare-metal Macbook pro (post-production 2011.7) as an example, the objective is to install the Macos and Win7 dual systems and implement multi-partition operations for Win7 at the same time.
1. First, use option to start the system and select wifi to recover the Mac system. This is Apple's strength. After the restoration, the system has a general Mac system. Www.2cto.com 2. You can use either of the following two methods. One is to use Bootcamp to install a dual system. This method is simple and convenient, but due to Mac control, this will have a certain impact on Win's performance, because this partition is equivalent to a ing partition. Another way is to use a third-party program refit to take over Mac startup, similar to the previous startup Manager software under win. You can use this third-party efi to directly select the partition from which to boot. The advantage is that you can directly read the hard disk. The disadvantage is that the driver is a little troublesome because it is not a BC simulation, so you need to find your own driver.
3. We adopt the common BC method. Next, you can have two options: Find the DVD drive installation system of Win7 Based on BC instructions, and find a way to bypass Apple's restrictions, I used a USB flash drive to install Win7. someone said that I could have used a USB flash drive? The one that only applies to the previous Macbook, the latest Apple does not support USB flash disks, even if you use the Win7 dvd usb boot program to write the USB flash disk as a boot disk, you can also modify the system file so that BC displays the "Win7 USB flash drive installer" (this is not displayed because it does not support newer versions, however, you can modify the BC configuration file and make a boot USB flash drive for you. However, you will find that the boot device cannot be found after the BC is restarted)
4. In addition, I tried to convert the USB flash disk into a GPT boot mode, and did not allow the mac to recognize this bootable device. Later, it was found that if win8 was installed, it would save more time and effort, because win8 efi could direct mac boot. The specific practice was to make a USB flash drive into a gpt boot disk, copy the win8 installer and start the installation. This is the charm of efi. But Windows 7 doesn't work, because the efi of Windows 7 is a version higher than mac (it can be seen that Microsoft is much more reliable than Apple)
5. We use a DVD disk to install win7.
6. The next step is to solve the problem of multi-partition. Many people say that Windows 7 can only be installed in one zone on mac using bc, which is totally a misunderstanding. Let's take a look at why they say this. Normally, a disk in the basic disk State can have only four primary partitions. Of course, if you can convert it to a dynamic disk, You can have N primary partitions, but your mac system is broken. Then, on the premise of the basic disk, two mac instances (one for EFI and one for MAC) have been used, so why are there two more? Isn't Windows 7 just one? In fact, this is exactly what win7 is doing. You can test it by yourself and find that if win7 uses a CD boot, it will be partitioned during the installation process, then it will automatically generate a partition of more than 100 MB (win7 indicates that the system is retained). This partition is a primary partition and is mainly used for guiding and pre-reading files. In this case, the system partition of Windows 7 will fill up the entire hard disk with four primary partitions. If you want to allocate the primary partition or expand the partition, the system will prompt that it will not work. Do you want to convert it to a dynamic disk? That is obviously not possible, because the mac is installed and cannot be started after dynamic conversion. (Remember that the extended partition is also the primary partition, but the extended partition can have N logical partitions ).
7. What should I do? Some people say it's easy to do. Isn't it enough to delete the 100 M partition of win7? Yes, but the deletion result is that Windows 7 cannot be started. Some people say that all Windows 7 partitions are deleted and then re-divided. This won't work either, because win7 will force another partition of over 100 M. So the correct method is: Delete the system partition of win7, click the partition of more than 100 MB, and use the "extension" option in the time zone tool for installation, extend the partition to the degree where the win7 system can be installed. This means that there are only three primary partitions left! Www.2cto.com 8. After Windows 7 is installed, you can enter the system. Whether you have installed Windows 7, you can use the extended tool to fill up the remaining hard disk space, right-click the "extended partition" and select "compress partition" from the menu. This is a tool similar to lossless file resizing. In this way, you can free up disk space and create extended partitions, then create a logical partition on the above, so that your win7 can have N disks available, and you do not need to heap them in a system disk.
9. Finally, I would like to remind you that most people in China use pirated copies. Do not activate Windows 7 using OEM spoofing during activation. In this way, the boot sector of Windows 7 will be overwritten. The result is that an error is reported when Windows 7 is started, we recommend that you use the method of shielding win7 activation detection for activation. Both activation programs are available online. If you have already covered the Boot Sector, you don't have to worry about it. After using the win7 installation disk to boot, choose repair system, Enter CMD, and use the bootsect command to forcibly repair MBR. Author's boiled peas _ network crawling
