  Causes and treatment with U disk reinstall the system can not find the following

  (1) The first reason: different patterns on the disk, U disk caused by reloading does not recognize the hard disk, since most of them are now computer''s hard drive serial hard drive, while the average XP installation disk and CD-ROM version of the GHOST, they are not integrated SATA controller driver (or sometimes also integrated, but with practice the SATA controller driver does not match), resulting in incompatible, and can not recognize the hard disk, leading to not be properly installed operating system or a blue screen, so it must be replaced hard mode, AHCI into IDE mode, the hard disk and can properly identify the normal installation of the system.

  At law:

  Press DEL, into the BIOS, find Advances --- Sata configaration - Stata mode selection-- will AHCI into IDE - F10 to save on OK, or select "Devices → ATA Drives Setup → Configure SATA as → IDE" Finally, press F10 to save and exit the BIOS.

  (2) The third reason: The master boot record MBR hard errors will cause does not recognize the hard disk installed with U, Jian Yi rebuild the master boot record MBR

  Approach:

  (3) The third reason: If WIN8 is preinstalled, but modified to WIN7, resulting in not recognize the hard disk installed with U, resulting in not installed WIN7, mainly because: due to the partition table is type carrying WIN8 GUID, and WIN7 only recognizes "MBR" type of partition table, so the only change the partition table types, we can identify the hard disk, you can normally install the WIN7.To be divided into two steps to:

  (1) Step 1: Preparation of PE GHOST system with a CD or a disk with a U-boot system, boot immediately press the F12 key, or set a good boot entry in the BIOS, after entering the PE, the PE is running below Diskgunius partitioning software, first of all, you can "delete all partitions" the hard disk.

  (2) After you delete the partition on the "change the partition table type" is the type that comes WIN8 GUID of change "partition table type to MBR".Since Windows 7 recognizes only "MBR" type of partition table.Change can come normal partition, you can normally complete the installation WIN 7.

  (4) The fourth reason: PE version is different U disk, will lead to not recognize the hard disk, commonly used PE is WIN2003PE enhanced version, as well as WIN8PE, low-profile election WIN2003PE more compatible, high configuration you chose to WIN8PE.

  The method of treatment can not find the reason for using the hard disk U reinstall the system as follows:

  (1) The first reason: to die with disk, U disk caused by reloading does not recognize the hard disk, since most of them are now computer''s hard drive serial hard drive, while the average XP installation disk and CD-ROM version of the GHOST, they are not integrated SATA controller driver (or sometimes also integrated, but with practice the SATA controller driver does not match), resulting in incompatible, and can not recognize the hard disk, leading to not be properly installed operating system or a blue screen, so it must be replaced hard mode, AHCI into IDE mode, the hard disk and can properly identify the normal installation of the system.
