subject: Rectifying Stop 0x0000007b Inaccessible_boot_device Error In Windows 7 [print this page] Serial Advanced Technology Attachment (SATA) is the new-generation drive interface used to connect the system with the storage devices. It is fast, compact, reliable with data transfer, and supports hot swapping. However, sometimes you face difficulty in booting your Windows 7 system. This may happen because of any hardware failure or hard drive corruption. In such cases, you should take remedial measures. However, if you are not able to resolve the issue then you should use a third-party hard drive recovery software to recover hard drive.
Consider a scenario wherein you have a Windows 7 system. In this, you have just changed the SATA mode of the system drive to use either the Advanced Host Controller Interface (AHCI) specification or RAID features. After that, you restart your system but it fails to boot. An error message is displayed, that is:
STOP 0x0000007B INACCESSABLE_BOOT_DEVICE
Cause:
The root cause of this error message is that the disk driver is disabled.
This issue occurs if the disk driver in Windows 7 is disabled. This driver must be enabled before you change the SATA/RAID mode of the boot drive.
Resolution:
To resolve this error, you should enable the driver before changing the SATA or RAID mode of the system drive. To do this, you should modify the system registry by performing the following steps:
Quit all the Windows-based applications.
Click Start, and type regedit in the Start Search box.
Press Enter.
Click Continue on the User Account Control message box.
Right-click Start in the Name column, and click Modify.
Enter 0 in the Value data text box.
Click OK.
Quit Registry Editor.
However, you should be careful while modifying the registry settings yourself. If you are not sure how to do it safely, you should consult a technician who should be able to do it more confidently. However, if you have valuable data and want to restore that first, then you should use a third-party windows hard drive recovery software to recover the trapped data.
