This significantly reduces the disk space needed to support the features, and makes recovery possible even on devices with limited storage capacity. Image-less recovery: Push-button reset no longer require or support a separate recovery image on a local partition or on media. What are PBR Textures? PBR, or Physically Based Rendering, is a model of shading used in computer graphics that more closely mimics the flow of light in the real world.The final result that we get in the material with PBR textures is also much easier to predict and much better to match with different variations of lighting. Thiscode locates and runs the first sector of.Next: Windows: Linux. The latter is newer and haslargely replaced LILO. These sectors constitute the first stage of theWindows boot loader which in turn loads one of two files depending on the version of Window:For versions of Windows up to XP, the file is loaded into memory.PBR then transfers to NTLDR.For Vista and subsequent versions of Windows, the PBR loads, the Boot Manager, intomemory and transfers to that.For Linux there are two popular boot loaders: LILO (Linux Loader) andGRUB (The Grand Unified Boot Loader). Such file-system-specific code would be too large to fit in thesingle 512 sectorInstead a specific diskaddress for the next 'chunk' is stored within the PPR.As mentioned above, the code in the PBR isspecific to the OS being loaded:For Windows the PBR loads an additional 16 sectors from the beginningof the partition. In general, the job of the code in thePBR is to load a slightly larger 'next-step' program.The code in the PBR can't read afile system's directory structure to locate this next piece of code toload. Whereas the MBR code isoperating-system independent, the code in the PBR is supplied by andworks with a particular OS. The MBR (or the GRUB chainloader) loads the PBR intomemory and transfers control to it. It is also sometimes referred to as the Volume Boot Record(VBR).

Partition Boot Record (PBR) Partition Boot Record (PBR)The partition boot record is the first block of any bootablepartition.
