The IdeaPad Yoga 11S is a compact ultralight hybrid notebook/tablet computer which released in 2013. Like the Yoga 13 and the Yoga 11 the Yoga 11S gets its name from its ability to take on various form factors due to its screen being mounted on a special two-way hinge. The Yoga 11S runs the full version of Microsoft's Windows 8 operating system ...
An external USB recovery drive is essential in case the data on your hard disk has been compromised up to the point where the system can no longer boot from the hard drive.

The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory. Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process.
The RAID drivers can be injected into the boot image on USB stick rescue media (though not on DVD-based media). In October 2016, Lenovo released 'LINUX only' versions of the BIOS for some of the affected machines. This BIOS adds the ability to switch the drive mode into AHCI.

A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
In Windows, if Secure Boot is enabled, all kernel drivers must be digitally signed; non-WHQL drivers may be refused to load. In February 2013, another Red Hat developer attempted to submit a patch to the Linux kernel that would allow it to parse Microsoft's authenticode signing using a master X.509 key embedded in PE files signed by Microsoft.
