Dell Inspiron N4120 Laptop installs XP, Win7 dual system process

I tried to put a dual system on my laptop many years ago, and I thought it was fun, or maybe I could use the XP system after all. How to do the wrong. At that time is in accordance with the online tutorial, thinking of using GHOSTXP system to install, into the PE system, at that time is very unfamiliar to these things, I inadvertently ordered an automatic partition of the things, Nimamamammamama ... , the entire hard drive has been formatted .... , and then especially hated the ghost method to install the system.

Turn to the point, now work after, usually also use the company's computer office, their computers are used to play games. However, I can not put the embedded things I have done before, so I want to go back to learn from the new. We all know, now a lot of embedded development software does not support Win7 system, there are a lot of hardware drivers do not support Win7 system, such as USB to the serial port or something. In short you can find a lot of reasons for you to install another XP system. Some days ago bought a mobile hard disk, want to put the XP system into, the hard drive to the area, the ghost system to restore, the results plug in the computer, set to boot from the USB mode, a ... The computer is blue screen. (here to explain this process in detail, originally I was looking for an OEM system, is relatively pure official system, using UltraISO to make a U disk boot disk, so a USB hole plug u disk, a USB hole plug mobile hard drive, where to find the boot key disk, set him to the front, the results can not, To be prompt system damage, or is prompted system ' txtsetup.sif is corrupt or missing ', here also changed a lot of format to write hard disk image, what usb-hdd+, Usb-zip are not, had to forget. Later think, is not the two USB hole conflict Ah, no way, can only be a different way, choose Ghost Installation. Here do not want to use the network of those inexplicable ghost system, so I made a, I first put XP installed on their own virtual machine, then ghost back up, and then export, yes, that is so frustrating. Then in the PE system to expand to their own mobile hard disk, but finally, although there is a boot interface, but then the blue screen. Some people say that XP does not support the USB type of hard disk, to modify the installation system INF file, attached Baidu Library link: http://wenku.baidu.com/view/b64f96f0cfc789eb162dc82c, modified after the new ghost file, Still can't solve the problem. Later on the Internet to see other people's comments, XP does not support from the USB installation, I really do not want to buy a CD-ROM, I would like to be able to make the volume of my USB flash drive as a disc format, the result of this USB drive ya have no production tools, attached to my hard disk and the picture, here is not advertising ah, just Too wordy, then turn to the point.

　　

Since the U disk can not be installed, then buy the CD-ROM Bai, bought their own burning. Then think about why do not have to put into the mobile hard disk that, in fact, there is no need, even if installed in their own computer can successfully start, in other computers open XP system, the system will automatically detect hardware, hardware does not meet or start, so it is a lot of trouble. I here computer originally is Win7 system, use of time also relatively long, simply put inside things cuff out, re-do system, to computer net body. According to the Internet, first install XP after install Win7 will be easy, in XP directly click on the installation of Win7 Setup files can be, and then did not succeed in doing so. When the installation of XP is still a problem, the computer loaded into the CD system files, or the appearance of the blue screen phenomenon:

Later the reason is that XP does not support the latest hard disk interface, that is, less drivers, here is to find a Achi driver installation files, or first to change the computer to ATA mode. I changed it to ATA mode:

Ok the next XP installation will be OK, and then under the XP system I click on the win7 Setup, suggesting that it is non-XP executable files or something. Forget, I will directly according to the normal installation method, I have built a two primary partition, Win7 installation of the time I choose another, but here I will certainly install the XP boot boot program cover out, but the relationship is not big, with EASYBCD software to restore a bit, This kind of recovery software with the interface is still relatively comfortable, after everything is done this way:

As for the AHCI drive problem after the solution, but I now use the feeling two modes no difference, there is a netizen to play a metaphor: like a person riding a bicycle, a person riding a tricycle in the F1 track race, the key is to see the hard drive speed, the interface margin is often very large. I try to directly modify the driver in XP, and there will be a blue screen phenomenon:

End of Count, enter XP or original drive. As for the PE under the software modification, but also tried, but did not find a suitable motherboard driver, so first use it, anyway also did not affect.
