Solved Dual Boot Messing Up My Clock ???

[lehnerus2000]

I notice that you're from Turkey, so maybe we are experiencing language syntax/translations issue.

Wow so you are saying Linux can configure offline settings of Windows OS i think you have no idea what we are talking about because we have now established Linux time settings could configures RTC not the Windows OS time settings.

I know that as I've personally had to deal with the issue.
You were the person who (apparently) didn't know that.

You also claimed that running the Linux installation on a dual boot system couldn't affect the Windows installation.

There is no way Linux or any other dual booted operating systems can alter each other clock that is been displayed this is a weird issue have a go at suggestions at below website link.

Now that you got caught out you're "changing your tune" in an attempt to make out that you didn't say that.

It's also ridiculously easy for Linux to manipulate Windows.

It would only take a few seconds to delete the Windows Registry files (configuration settings).
I suspect that Windows would "throw a major wobbly" next time it tried to boot.

OTOH, it would be tricky (not impossible) to use Linux to set a specific value in the Windows Registry.

Hi MSClin,

As you can see you have not mentioned about Linux modifying RTC chip setting.

MSClin did mention the hardware clock in this post:

Everything Megahertz07 said is true... At least read the link which Megahertz07 pointed to. I will even quote the answer from there:

If you have multiple operating systems installed in the same machine, they will all derive the current time from the same hardware clock: for this reason you must make sure that all of them see the hardware clock as providing time in the same chosen standard, or some of them will perform the time zone adjustement for the system clock, while others will not. For example, if the hardware clock was set to localtime, more than one operating system may adjust it after a DST change, thus resulting in an overcorrection; more problems may arise when travelling between different time zones and using one of the operating systems to reset the system/hardware clock.

This is the simple explanation to the problem the OP have.

The simplest way to affect the RTC is to let the operating systems do it (by applying the changes mentioned earlier in this thread).

This wouldn't be an issue if Windows Time-Synched when it booted (there is a task for Time-Synching).

Well for my two cents worth the topic has got into some deep and meaningful stuff and personally my dual boot 7 and Linux Mint 18.3 Cinnamon are on the money re time and date maybe it is the Zorin OS putting things out of whack I found it a bit of an unstable system personally.

I can read english very well and understand what i'm reading but i do have problem with writing english.

You are having problem understanding what i have tried to explain yes we can use Linux to delete or modify registry but by default Linux will not automatically do that it will also will not and cannot modify Windows settings we can modify Windows settings using registry from Linux but does Linux have software to manage Windows registry i have no idea if it does guessing by default it does not.

I have reply to MSClin post where he has not mentioned RTC chip been modified by Linux if you look at the post #6 you will notice he has not mentioned RTC chip been modified by Linux i have reply to him at my post #8 .

It was @Megahertz07 who has mentioned RTC chip been modified by Linux i first did not agreed with him but looks like he is correct and i was wrong we all learn new thinks everyday this is not a big deal.

Just thought I'd mention that I did use Linux Mint 17.3 in a dual boot with Windows 7 a while back.

And, when I finished installing Mint 17.3 (after Windows 7) I noticed that the time was correct for both Windows and Linux Mint.

From memory, I believe Mint 17.3 changed UTC to "no" in /etc/default/rcS without me having to do it manually when Mint was installed in a dual boot with Windows. The earlier versions of Mint didn't do that.

Then, when Mint 18 was released, it was back to the having to edit /etc/default/rcS manually (or something like that). I haven't used any of the more recent versions (18.1, 2 or 3) so I don't know what the situation is with time and dual booting Windows with those.

Rather than spend time arguing amongst yourselves, would not be be better to simply help the Original poster. This help has been provided so it's best to just monitor the thread and assist BuckSkin to enter the Linux commands to adjust the scheme his Linux install is using to match the one that Windows uses if he asks for more help

 

[Megahertz07]

Nigel, we all learned something on this thread.
- Not only the OP, but I, and many of the involved, learned how to Linux use the local time (thanks to MSClin).
- FreeBooter also learned something (more than the thread itself). I have to consider his skills on fixing disks as Jumanji said he did a good job on another thread.

 

[ICIT2LOL]

I agree Nigel and again for what it is worth I still think Linux Mint 18.3 Cinnamon or MATE would be a better alternative to what the OP said he had put on his machine and my impression was that it isn't so much of a hardware or firmware problem so much as a system one because I had problems with Zorin both as a stand alone install and dual boot.

So my advice for the OP is still to try the Mint preferably the Cinnamon version in preference to Zorin which I think has a few bugs well quite a few bugs to be sorted out before it is stable enough for at least me to try again.

Fair enough.
I've edited my original post.

I had to apply the fixes (mentioned earlier) starting with LM18.

In-place LM upgrades have retained the modified setting.

1. Edit "UTC=yes" to "UTC=no" in /etc/default/rcS.

Alternative way to make Linux use Local time (working only on newer Linux distributions):
Open Terminal and type this command - timedatectl set-local-rtc 1

Thanks again.

The second option is the one that worked for me (and, as far as I understand, for all more recent Linux installations) timedatectl set-local-rtc 1

I have since booted back and forth several times with no more clock problems.

I still think Linux Mint 18.3 Cinnamon or MATE would be a better alternative because I had problems with Zorin both as a stand alone install and dual boot.

Thanks for the recommendation; no more than I have messed with ZorinOS, I have decided it must have some problems.

It is my first ever attempt at dual-booting and my first ever experience with any kind of Linux; I chose Zorin mostly because it was recommended to be most like Windows 7.

The first couple weeks, I could click on "Network" or "On This Computer" in Zorin and access anything anywhere on our four machine network; I could manipulate files or whatever as easy or easier than I could on any of the Windows machines; then, just out of the blue, it will not access anything but itself.

Also, more as an experiment than anything else, I used "Wine" (or whatever it is called) to install the Windows program "FastStone"; I had a FastStone desk-top icon and everything worked fine; then again mysteriously, the FastStone icon disappeared from the desk-top and I can find no trace of it ever being there in ZorinOS.

I believe I will follow your recommendation and download this Cinnamon business and give it a try.

I may also look into this MATE that you mentioned.

 

[ICIT2LOL]

Ok mate well Cinnamon and MATE are basically the same system just more or less a different GUI I prefer Cinnamon you might like MATE both are very 7 like anyway.

if you want a good video to watch this is the one I used How to Dual Boot Windows 10 and Linux Mint - YouTube Now I have to say my attempts to dual boot took a long time because I think the BIOS being EUFI mucked me around a bit so if you have an EUFI BIOS you will need to set it to a legacy one.

Disable Secure Boot and enable CSM is the usual thing to set in your BIOS of course if you already have a legacy BIOS then you will not have to bother. I will tell you it took me over ten times to get the dual boot going but again I think it was my machine but do keep trying if it doesn't go first try
My suggestion would be the latest Mint - 18.3 and one of those varieties it is purely personal.

The most recent that I am seeing is 18.3 Cinnamon "Sylvia" ; I read a few comments that liked whatever was before Sylvia better; what are your thoughts on this ?

I know absolutely zero about any of this; I picked up some second-hand HDDs and have been using them as guinea-pigs; if something goes haywire, I can just wipe the drive and try again, while my system is safe on several other HDDs; this way, I can learn without getting burnt too bad.

That is the best and safest way to do it. I recommend that you detach all other drives when installing Linux.

I've been using Ubuntu, Xubuntu and now Lubuntu, that is based on Debian, for more than 10 years.
Zorin is based on Ubuntu, and many friends like it.

 

[ICIT2LOL]

Yep well as Megahhertz has said there are a lot of options out there and I think when I looked last there were more than a thousand version of the original system. I did a lot of testing on the various systems agreed not to the extent that some of the older hands at Linux have and I found that in general the larger the ISO download it occurred to me the better and a little more sophisticated the system became so at 1.8GB 18.3 was ahead of the pack so to speak.
There are systems that frankly were a little "basic" and some that were downright odd for what I wanted but I am by nature a tad pedantic in researching what I do re systems hardware etc etc and what I install.

Now you might like Zorin so go with it don't let me influence you by what I like and I can only say since dumping Windows that I originally settled on 18.2 Mint and then I tried the beta version of 18.3 Mint and when it became a release I went for it originally the MATE but then the Cinnamon simply because I find the GUI a little less cluttered not that it is much of that it in my mind at least the nearest thing I am going to get to Windows 7 which I think we all would agree is probably the best system that Microsoft has put out.

Just as by the by if I were to choose another Linux set-up I would go straight Ubuntu the spin off's are ok but you have to know that the basic Ubuntu has not changed insomuch that it still keeps it's core value by that I mean that it hasn't really changed a lot and what there has been is all good.

Now one last thing I will add is that you can go ahead and get a spare drive and try as many of the systems as you like as I did it because at least unlike the Microsoft stuff it doesn't cost you anything and you might just find exactly what you are looking for. Of course it depends on how much of a rush you are to find the right system because testing the different ones out does take some time but in general I think the more you invest in researching the different systems the better outcome for you will be.

Good luck and please don't be influenced purely by what I prefer.
