You cannot use ultraiso to burn XP to a USB flash drive.

In recent years, the capacity and price of USB flash drives have been increasing in inverse proportion. It is really close to the price of cabbage. Therefore, many friends prefer to use USB flash drives for system installation, after all, because the CD is not very convenient to carry, and some machines often do not have the most important optical drive, we often use the ultraiso software to burn a USB flash drive for installation, but it is found that XP is always installed with an error message: "inf file txtsetup. sif is invalid upt or missing status 18 ". In this case, we often doubt whether the file is actually lost. We immediately open the USB flash drive, but find out how to check whether all the files are in.

We can't solve this problem for many reasons. The reason is that ultraiso does not support Windows XP for burning hard disk installation disks. You can burn either Vista or Windows 7.

Solution to this problem: we can download another software named "winsetupfromusb" and burn it to XP. The installation package can be searched by Baidu. There are a lot of green versions available on the Internet.

Many other computers do not need to change the BIOS when selecting the boot mode. We only need to press the F12 key when starting the system to bring up the boot menu and select the appropriate method.
