Install dual systems (Windows and Linux) and even multiple systems under virtual machines using a USB flash drive

Fortunately, before you begin, install VMware Tools software so that virtual machines and hosts can share data, files, and so on how to install the system using a USB flash drive under a virtual machine: 1, the U disk must be recognized on the host (not the virtual machine system) 2, U disk must be in the form of mechanical hard disk to add a hard disk to the virtual machine set 3, set boot to the USB flash drive on the virtual hard disk 4, the front three steps to ensure that your USB stick can boot the installation system (using the soft disk to burn, do not need u start OH) If you follow the above steps, you fail, Please Baidu but even if you have installed the system in accordance with the above method, once you unplug the USB stick will not be able to enter the previous installation of the system: I personally think is to guide the wrong http://win8e.com/pc/xitong/11141.html5, The above error is obviously your boot installed on the USB stick, how to determine this? You take the physical machine (the same as the virtual machine) to try to boot from the USB stick, you will find that the USB stick can not boot (this is because your USB stick boot (that is, MBR) is modified) solution: In the installation of Linux system should pay attention to the boot installation disk place, do not select the disk of the USB flash drive. 6, after the installation of the system, (adjust back to the original disk boot (not new)) in the security situation to remove the USB flash drive 7, after you remove the USB flash drive, you open the installation of the dual system, will show a virtual disk file can not find (in fact, the new USB stick is not found), then do not panic, What you have to do is to delete the newly created disk on the virtual machine 8, delete, will not appear the virtual disk can not find the hint, re-boot, you will magically discover the double system success, congratulations to you, Success Note: 1, MBR guidance problem you can refer to the following page 2, the installation process I found that     When installing the system as usual on a virtual machine, you will find that some steps and procedures for installing the system are gone (as if it were skipped), which eventually led to the step of setting the boot installation location skipped (this is critical and deadly) Later, combined with their own experience to conclude that my Computer configuration is too slag, 2G 1066MHz of memory is completely unable to support the steps of 3, U start (U-boot) can not need U-boot production tools, using a soft disk and other burning writing disc image can also boot the system 4, one-time BIOS primer Guide seems to be wrong, then do not worry, you directly into the BIOS, permanent modification of the boot sequence is good 5, the virtual machine system and the data between the host can not be shared resources, you'd better install VMware Tools Software 6, in the BIOS do not understand English, do not change, to change also the best Baidu Think about VMware player booting from USB stick on virtual machine installation WAdvantages and disadvantages of in8.1 system         VM Virtual machine settings boot from USB flash drive installation win8.1http://win8e.c Om/pc/xitong/11140.html as stated in the first half of the above article, we normally install the system in the virtual machine as shown in using the ISO image file directly. This is a good way to complete the installation and use of the VM virtual machine, and booting will not be a problem. However, once the "USB flash drive to the virtual machine system" is chosen in this way, a series of problems will arise. The most important problem is: After you unplug the USB drive, the virtual machine installed system will not start properly. As shown, because the startup item is the first boot item with a USB flash drive. So this time the error, the virtual machine can not open. If you modify the startup item, put the virtual disk in the first place, put the USB stick in the second place, is not solve the problem? The answer is NO! WIN8E Small series continue to try, such as on the modified order, do not plug in the case, we see this screen. That means it didn't work. Booting from a virtual disk is not successful. That plug in the case, let the BIOS startup item in the virtual disk before the USB drive that disk, what is the situation? The answer continues to disappoint! It seems that the so-called slave drive starts below the sub-classification only the first one is valid. If the first one does not start successfully, skip the second, third, skip to the Next big class, CD-ROM, and skip to network boot from Intel e1000e. Hard drive several side-by-side, will not be tried in order. There is also a hint that you are using a SCSI physical disk when you open the virtual machine. SCSI physical disks have low dual-boot performance. The installed operating system may not boot properly in the virtual machine. However, if used only within a virtual machine, the SCSI physical disk will function correctly. What if you remove the Scis hard drive from the set up virtual machine to add the USB flash drive? Can the system that is installed in the virtual machine start normally? The answer is NO! After you delete the hard drive, there is no second SCSI project in the BIOS. The virtual machine's virtual disk has been installed without booting the system. is not recognized, continues to be the diagram of the second case above. Operaing System not found.To this win8e small series has been brought to understand the VM virtual machine with a USB stick installation system defects. If you unplug the USB drive, the virtual machine will not work. Do you want to fix the system boot so that it starts normally? So why not start loading the ISO installation? What do you do with the second virtual hard drive? The answer is, play! Supplement 1: Has encountered the removal of the USB flash drive can not open the system of the virtual machine classmate may solve the problem, first plug in the USB stick boot into the system, download EASYBCD installation repair boot boot to the C drive. Then modify the BIOS so that the virtual hard disk priority is higher than that of the USB stick, specifically 0:0 on 0:1 above. Unplug the USB drive to see if you can enter the system smoothly. If you can prove the success of the boot, you can now delete the new hard drive set by the virtual machine. The BIOS does not have the tube, 0:1 that one item automatically is gone. The repair work is complete.   The above phenomenon I have another explanation: is your new installation of the system boot is written to the USB flash drive, not your first system on the disk (hard disk) above, that is, the MBR installed on your USB drive disk above, this is wrong, because the MBR is not a file, So you can't copy it from the USB stick to the disk on your first system. Because your u disk's MBR has been modified, so before the start of the U disk (U start) will not have, the next time your USB stick can not be launched as U. So you pull the USB flash drive, the virtual machine on the new installation of the second system will not be able to go in, as well as you can not choose from the physical machine U boot into the USB stick thing. This problem occurs because: when you install the Linux system, you do not pay attention to the location of the boot installation, leading to the MBR directly installed on your USB flash drive, so pay attention to the details (about the Linux installation of boot options on the Linux partition after the end of the next interface)    Please use the USB stick to install Linux and Windows dual system on the virtual machine.
