recently idle nothing, I want to install a Ubuntu dual system under Win7, the result took two days to do a good job (reloading the system in the middle), as a program猿 猿 , 实 Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Win Tools to install, interface operation, simple (recommended method). 3. The wubi (Windows Ubuntun-Based Installer) method provided in the Ubuntu image file has not been tried. Since there are many installation methods on the Internet, they are not summarized here. Here are just some of the problems and solutions encountered: 丨System Environment 丨Win7 Ultimate 丨ubuntu-12.10-desktop-i386.iso Desktop Edition 1 . When you compress a disk for Ubuntu, all disk types become dynamic (normally basic). The dynamic type has its disadvantages. It seems that it is impossible to install dual systems (we just want to install dual systems, this is not a slap in the face), and the benefits do not seem to us. Specific solution: It seems that only the format of all the discs, reloading the system (someone on the Internet said that reloading can not be dynamically transferred to the basics, I do not know if the person who said this has personally tried it, I only know that I changed to become basic after reloading. As for whether you believe it or not, anyway, I believe it~). 2. Error 17: Cannot mount selected partition This configures (hd0,0) incorrectly for you, that is, you store the vmlinuz file, the initrd.lz file, and the iso file directory disk. (hd0,0) is C:/, (hd0,1) is D:/. In the error prompt interface (should be this interface), press e, then press Enter to enter the editing interface. Change 0 in the (hd0,0) to 1 or 2... (that is, you store the order of the previously mentioned files. ), then press b to save and restart. Try it slowly, there is always one right. 3 .Error 15: File not found Here should be title Install Ubuntu root (hd0,0) kernel (hd0,0)/vmlinuz boot=casper iso-scan/filename=/ubuntu-11.10-i386.iso ro quiet splash locale =zh_CN.UTF-8 initrd (hd0,0)/initrd.lz The vmlinuz and initrd.lz keywords in the configuration information are the same as the file names in your iso image file. The version I installed is 12.10 vmlinuz There is a suffix, it seems that the 12.04 version has no suffix. Pay attention to the specific configuration. 4. As mentioned earlier, reinstalling the system once, this is a problem encountered in reinstalling the system. I reloaded it under pe. After re-partitioning under pe, I said that C is not a warning of the system disk when reinstalling. In short, it cannot be installed under the C drive. Specific solution: use the system general installation tool under pe, find the file under the resource suffix of im7 in the win7.iso image file (specifically can not remember), load to the C drive, load and restart to enter Installation interface, perfect installation.
