Troubleshooting Operating Systems Part 4 Now that we've identified common issues that occur with our operating system, we are ready explore the tools that will help us in resolving these issues. After completing this segment you'll know all about the Recovery Console and create a new partition to serve as the boot sector, correct master boot record (mbr) issues, how to create a disk repair & perform a disk repair, what MSConfig is, what defrag is and when/why you would use it.

Video Transcription

00:04
So now that we've taken a look at some of the issues that we may encounter with our operating system, let's take a look at some of the tools that we may be able to use in order to solve this or be able to investigate it further.
00:13
Now, our first tour, we're gonna look at his recovery. Consul Overcovered Consul is a disc that weaken boot to outside of having to boot the operating system on our drive and attempt to attempt to use the recovery consul to recover data, run a command line or run applications and run recovery programs.
00:33
Such a CZ
00:33
fixed boot and fix nbr
00:36
fixed boot is going to write a new partition to our boot sector on allow us to use that partition in order to fix nbr fix nbr. We can repair the master boot record s o. We may want to try our fix nbr. We wouldn't try to repair our master boot record so that our operating system boots properly
00:56
on or we may want to try our fixed boot and write that new partition to our boot sector.
01:00
This is going to allow us to if our boot sector is corrupt or if our master boot record has been malformed or it's been infected, will be able to use these tools in order to reset that and get it back going again as long as our tools can recognize that there's an operating system on our drive
01:19
that they can use the fixed boot or fix NPR in reference to
01:23
we also have our SFC or System file checker, our System file checker. We may be able to run from our operating system are let it know to run the next time we restart our computer or we may be able to re run it, run it from our recovery Consul Recovery disc. Our system Final Checker is going to check the
01:41
files necessary for our operating system to run.
01:44
That's going to check the critical files that are operating. System needs to boot properly. It's get going, and it's going to see if there's been any changes to those files. If there have been, it may be able to actually make money. Under those modifications, it may be able to restore those files back to how they were before
02:02
and with using a system file checker
02:05
and telling it to check for any issues and then fix. If it can, we may be able to get back up and running with our operating system.
02:12
Then we have repaired disc repair Disc is a disc specific for our version of Windows seven or Windows X P R Repair disc, maybe the same similar just that we use for installation. We put our repair disc inside our computer and little tent, and it will give us applications.
02:31
Such is our recovery consul in our system file checker.
02:34
Or it may even attempt to automatically recover Windows and any attempt to automatically repair windows. So if we run into an issue where we have a certain we have a certain part of our operating system missing, we have a critical file missing or we're not sure why are operating system is It's booting or starting. We may want Thio put in our repair disc,
02:53
keep one of those handy
02:54
and then sticking in our computer boot to our repair disc and use the appropriate repair utilities in order to try to repair our computer and get our computer up and running and booting again.
03:06
Next, we have a pre installation environments Windows pre installation environments, also known as Win P E, allows us to have an environment where we can boot
03:15
onto a disk. We can have a system that we boot into. That isn't the operating system installed in our drive. The pre installation environments are excellent for backing of data running command line utilities, or we also use our wimpy environments are pre installation environments
03:35
for deploying our operating systems. We may use our wimpy environments to build
03:38
the basis of our system deployments off of if we're using a centralized deployment server. So we want to keep those in those pre installation environments in mind. Win P e environment is not a complete operating system. We wouldn't run that in place of, say, our Windows seven or Windows Vista.
03:55
But we would use that if we were trying to have some wayto
04:00
navigate through our drive and interface with our disks without having thio completely on re installer disks or amount, and then mount that drive on the different computer.
04:13
Next up is M s can thick M s config allows us to change boot and start up configurations such as which service's or applications we want to start at start up, and we can also change how our computer will start the next time we boot. We can tell it to start in safe mode the next time we boot. Or we can sit
04:30
custom configurations for how our computer will start
04:33
changing which service is load or which programs start. And this allows us to have greater control if we're trying to diagnose a particular issue. If we want to eliminate certain variables and eliminate certain service is to try to figure out what's going on with our system. MSK in pig is a great tool to help customize
04:53
how we're going to boot the operating system the next time around,
04:56
and we can use that again for troubleshooting or to eliminate variables. We're trying to figure out a new issue on our operating system.
05:03
Then we have defrag. We talked. We talked about the fragmentation a few times when we defrag. Our disc were essentially taking all the fragmentation that occurs when our disk reads and writes data, and we're trying to consolidate that into different sectors. When on disk reads and whites data, it places it all over the place.
05:24
It does this so that it can read and write quicker.
05:27
It doesn't have to search around and say, Okay, you're trying to write this data. Give me a second while I find what I put the other data like this. It's not gonna do that. Our Dr can't anticipate
05:38
the types of data that we're gonna write it can't anticipate that we're gonna write more of this type of data or data associated with these files. So all I can really do is write the data right now and then read it and search for it later.
05:51
Defragment ation allows us to speed up our drive if it's severely fragmented by taking our drive, and I'm giving an opportunity to soar clean house to organize his bookshelves. So if we noticed we're having a lot of drive hard drive problems if we are noticing we're having issues that we referred to earlier as possibly being related to disk deep
06:12
our disk fragmentation,
06:14
then the defrag utility will allow us to check and see if our disk really is fragmented. And if it is, clean it up
