4 primary partitions installing xp to one of it this enough ?

and why it's limited after I send post not before ? WinSetupFromUSB_1-0-beta8.exe but I'm sure it's not the program bug because I did unpacked iso to usb manually and got absolutely same

wtf why topic tittle so short ?

Seems like copying files works fine: PAGEFILE.SYS and WINDOWS folder created on targed partition but only it. All other files like boot.ini ntldr and bootsect.dos and some others appears on usb without any error message. After reboot no more possible boot in any way: HDD or USB installer.. Is it known bug ?
