First Use Usbwriter. Make a Startup disk.
Insert a USB flash drive.
When installing under VMware: Add Hardware--choose to use a physical disk. In the drop-down box for the device: a PhysicalDrive1 appears. (It is the logo of the USB stick, if my computer except the USB stick, only a disk.) If the number of disks behind the disk will be +). Then, start the virtual machine and quickly press F2 to adjust the BIOS. (vm0:1). Start the installation.
In the VirtualBox under the trouble some:
You need to make a virtual hard disk first. Through DOS commands.
Turn on DOS first: Enter the VirtualBox directory:
Vboxmanage internalcommands createrawvmdk-filename Virtual Disk file name-rawdisk device path
The first parameter is the full path and file name of the vmdk file, and the second is the specified disk device path, because the USB drive that you just saw in Disk Management is disk 1, so write \\.\physicaldrive1 here. (The number here is to see how many disks you have.) The default USB stick is on the disk basis +1, the disk generally starts from 0 counts. I just a piece of disk so: 0+1)
- Then turn on VirtualBox. In the device-"Assign optical drive-" The virtual disk file name just made.
