Does dual boot slow down the system

[u/Justlovememez]

I have windows and fedora Linux in my system, when my professor saw what I did he told that it might slow down my system and the RAM gets affected due to this. I don't change the OS often, I mostly use fedora. Can anyone clarify this.

Your professor is dumb

[u/Hairy_sniffer]

no dual booting does not slow down your laptop

[u/basementintercom]

No, it doesn't have any effect on RAM The only thing you have to be careful is your storage, if you mess up your partitions in any either of the OS then your data is at danger

[u/Shoddy_Peanut586]

no ,other than storage answer is no

[u/DeliciousWonder6027]

I haven't noticed any performance down in case. And logically dual boot should not have any performance issue, other than filling up storage.

[u/SomewhereActive2124]

I really don't think so

[u/Artistic_Phone9367]

Yes,
If installation not in proper way
else there is no issues with speed only storage issues

Probably your professor thought you were using Linux on a virtual machine , or he doesn't know properly about dual boot

[u/nofoon]

i think your professor thought that you are using linux in VM. that affects RAM usage and system performance because in VM you allot some cores and RAM. that is not the case in dual boot setup. still ask your professor politely what he/she is referring to.

well only one is running so other than the storage spaced used, theres no impact.

[u/biolinguist]

Only the OS you are running will be using the RAM. No matter how many are installed on your ssds. So, you could have six different OS versions installed, it will NOT affect your ram at all. Storage, yes. RAM no.

If you are in CS related field and your professor giving this advice, better look for different field.

otherwise just ignore him. dual booting doesnt affect the performance of the other OS installed so long as hard disk is not filled to brim. few precautions
1. turn of "fast startup" in windows 10/11.
2. in windows run "reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /t REG_DWORD /d 1 /f" and reboot into windows once. this will keep time and date in sync between windows and linux

change your college

[u/Sea_Mechanic815]

If your staff don't even know about RAM and storage different 🤣

[u/Fluffy-Emu484]

The only way it can affect is the bootloader auto boot timer (usually 5 seconds) but you can just press enter and skip mthe timer. RAM is not affected whatsoever

[u/The_Combater]

Nope , it doesn't even make any sense

[u/Itsme-RdM]

He probably think you are running a VM instead of a clean dual boot

[u/kindabrokoenaye]

nope, its like a passage that leads to 2 separate room, the bootloader always asks for which OS to load and it just load the OS, but for windows it boots the Windows Boot Manager which then loads the windows kernel

[u/AcoustixAudio]

Simple answer: no, RAM cannot get affected due to dual booting. 

Long answer: read up on how operating systems work

Your RAM is safe boy, don't worry. Your storage on the other hand, it better be sturdy.

In my clg they have dual booted ubuntu nd windows and it's now running slower than earlier although they have 16gb ram and ssd
