Boot Windows Oops, we get this horrible error! new method

Whenever you use a partitioning tool against an installed system, there's a chance of a problem, filesystem corruption and who knows what else. There is no guarantee for success. Re-partitioning of installed operating systems is risky. This is why you should always create your setup BEFORE installations, so you never have to face this kind of problem. Repair unbootable Windows installation Following the instructions, we will boot from the Windows installation disc. Click on Repair your computer: And you will see this menu: Let Windows repair itself. It should do a pretty good job. Indeed, we're up and running. Windows 7 will start booting and recommend you run check disk against your disk, offering yet another hint that the resizing procedure messed things up a little. You should indeed let the tool run. And soon, you'll see the login menu: And here we can see the changes in My Computer and the Disk Management. One thing that Windows 7 does not report corr

Lab. No 8 Shortest Job First Operating System

Lab. No 8 Shortest Job First Shortest-Job-First (SJF) is a non-preemptive discipline in which waiting job (or process) with the smallest estimated run-time-to-completion is run next. In other words, when CPU is available, it is assigned to the process that has smallest next CPU burst. The SJF scheduling is especially appropriate for batch jobs for which the run times are known in advance. Since the SJF scheduling algorithm gives the minimum average time for a given set of processes, it is probably optimal. The SJF algorithm favors short jobs (or processors) at the expense of longer ones. The obvious problem with SJF scheme is that it requires precise knowledge of how long a job or process will run, and this information is not usually available. Like FCFS, SJF is non-preemptive therefore; it is not useful in timesharing environment in which reasonable response time must be guaranteed.
