Urgent!!! How to install the system with a USB flash drive? High Score Feedback! 50

With image installation, a simple 700m is definitely enough. Copy the ghost version of the gho file and you're ready to go.

1G is definitely enough, the main thing is to boot from the hard disk to start from the U disk to start from the U disk in addition, you can put a Windows pe in the U disk, only more than 20M, a simple operating system, you can do simple operations on the partition installation.

1. First of all, you must determine whether your book supports U disk boot (you can see it when you enter CMOS), only those that support U disk boot will do;

2. To determine whether the USB flash drive (mobile hard disk) supports booting;

3. Use PQ and other disk utility software to set the mobile disk as the active partition;

4. Use a mobile disk to make a startup installation disk (different systems);

5. Enter CMOS and set it to U disk to boot;

6. Insert the mobile disk and restart.

The size of the portable disk (USB flash drive or portable hard disk) is related to the system you want to install, if the original installation disk is more than two discs, 1G may not be enough, if there is only one CD, 1G is enough.

Are you talking about a USB flash drive PE system???

Go check it out, there's a tutorial!

The principle of installing the operating system through a USB flash drive and a CD-ROM is the same, and the installation method is very similar, and their main differences are:

The disc is cheaper, and a blank disc is less than 2 yuan. In comparison, the ** of the USB flash drive is slightly more expensive.

Once the data is written to the CD, it cannot be modified, so putting the operating system on the CD can effectively prevent the system files from being modified by anti-virus software or other misoperations. This is both the advantage of the disc and the disadvantage of the disc, the U disk can also be erased and written into other data after the boot data is written, but the ordinary CD-RW disc is burned at one time, and the burned data can no longer be modified and erased.

In the process of preservation and use, the disc is easy to be damaged due to wear and tear, compared with the USB flash drive, the reliability is better, and it is easy to carry and preserve.

The speed of reading data from a USB flash drive is generally slightly higher than that of a CD-ROM disk, which means that the installation speed may be slightly faster than that of a USB flash drive when using a USB flash drive installation system.

U disk installation system is very convenient,Very fast,XP can be done in a few minutes,Win7 15 minutes to get it,Unlike CD,To do half an hour not to say,But also to pay,Use U disk,Go to the relevant mirror on the Internet yourself。

And the most important thing is that if you use an optical drive, it will hurt the optical drive, especially the notebook, once there is a problem, it is very troublesome to replace it, and it is very expensive! In some cases where you can only use the optical drive, there is no place for you to cry.

1. The U disk installation system is convenient, and the system files can be redone many times.

2. Fast running speed.

3. It is not easy to wear and damage, and the disc is generally installed several times.

4. Many notebooks do not have an optical drive, and the U disk will play a role.

5. U disk installation system is the development trend.

After it is installed, it is the same, and the U disk is easy to carry, so as not to get in the way with a plate.

This one is simple. You can take a look at the blog below, which is very detailed.

Hope it works for you.

The PC cannot be used as a USB flash drive, and the system can only be installed using the USB flash drive as a CD.
