I want to Install UbuntuServer 21.10 as dual boot system of


Product: HP Pavilion Elite M9372.GrDesktop PC 2008-2009
Operating System: Microsoft Windows 10(64-Bit) Home
PC is Intel Core 2Quad / RAM 8GB DDR2
can I without problems...?

Can I easily >>upgrade-to>> Ubuntu Server 22.04 LTS # April 2022, via CMD line when time comes???

I will use it as Always ON as LocalLAN File/Media Server, is any limit required for staying always ON... eg Operate max of 3-days always ON...??
Alternatively,
What about using
Wake-On-LAN, with an ETHERNET USB-2-Ethernet adapter for connecting to this desktop PC...? Ubuntu Server 22.04 LTS supports Wake-On-LAN or this is hardware only compatibility???

On WOL: https://help.ubuntu.com/community/WakeOnLan

On installing 21.10 as a server... 21.10 is an interim build support wise. LTS version are support better for security updates and stability. In Server Editions, that is usually what you want and depend on. 'Stabilty." Whether you install 21.10 or 20.04.3 LTS, come late April, you can update to 22.04. Even if you do decide to install Server 21.10, wiht the intention of updating to 22.04 LTS come April, on that release Upgrade, I would change the APT option to upgrade on LTS, instead of interim test versions.

On dual-boot server intended to be as a dual-boot with Windows... ??? Why??? Those two functions sort of conflict with what you have said you want. Just saying that the logic of what you said is not there.

If 24x7x365 uptime for Server Sercies then what instances do you see yourself bring it down, for use as Windows 10? To make the Ubuntu Server Services available when you use Windows 10, you know that if you ran Ubuntu Server as a VM on Hyper-V, with boot VM on boot, you know you would have what you said you want as a goal, right? Just going off what you said you want...

Even for setting up a Hyper-V guest as WOL, if you have more than 2 NIC's that support WOL. Because Hyper-V is going to need the NIC with WOL capabilities, physically passed through to the specific VM that is going to use that...

+1 on not installing a non-LTS release. Start with 20.04 then wait until late-June, early July, at the earliest to upgrade/install 22.04. Give it a few months to settle and for some early issues to be resolved.

I wouldn't deal with the complexities of a dual-boot setup especially if the system is going to be always on as a media server.
There aren't any arbitrary time limits for being powered on with Linux systems that I'm aware.

$ uptime
 20:19:08 up 9 days

is my media server (Plex, Jellyfin, MPD and some custom music tools), NFS, calibre and TV recording box. It also runs a Nextcloud virtual machine.

$ virsh list

----------------------------------------------------
 1     nextcloud                      running

9 days ago, I happened to patch and the patching needed a reboot due to a new kernel, so I rebooted it. It is always on. It doesn't sleep or WoL. Always on and I prevent the HDDs from spinning down too. Lots of processing happens overnight on that box. I never know when it will be recording some TV show. I tend to get PBS shows after midnight to avoid having too many concurrent recordings during prime time.

Also, it 'pulls' backups for a few systems overnight here. It isn't my main backup server, but I'm moving more and more over to a dedicated disk inside it for some not-so-simple reasons. I really need to move it from 18.04 to 20.04, but because it is needed to keep the "one who shall be obeyed" happy, I need to schedule it being down MONTHS in advance if I want to wake up ... ever. Mujer feliz, vida feliz.

This is very old PC(BIOS Firmware), 2008-2009, after dual boot Windows 10 Home + Linux Server 21.10/22.04, can I set the default boot OS…?

WOL
May Not supported…? If in this PC wake on LAN - request wake up eg from my laptop - should boot the default OS, if dual boot system, correct?

Because this PC is very old, and Windows 10 Home, I think Hyper-V Not supported, but ONLY VirtualBox is supported as of running VMs…

With this in mind,
Can you reply with less words, what you wanted to say…?

Yes, you can have grub boot whatever OS you prefer as the default.

Win10 wasn't released in 2010. Do you mean Win7? I'm always amazed when people read MSFT EULA and agree with the updates/changes forced in Win10. I didn't accept it, don't have Win10 for that reason. It was some nasty legal terms, IMHO. Completely 1-sided. Anti-consumer. Anti-privacy.

All Core2 Duo systems are 64-bit and the CPUs support VT-x - which is the hardware support needed for running any of the modern virtualization hardware. However, sometimes "bad" companies like HP and Acer removed from the BIOS the ability to enable VT-x support even when everything else in the system supported it. I've seen this on laptops from both those companies. In fact, some Celeron CPUs have VT-x too. The first Chromebook I owned did while Intel was trying to figure out what to charge for fast, cheap, CPUs across their line of CPUs. Also had a $50 Pentium from 2015-ish which was faster than all the Core2Duos, supports VT-x and happily ran 3 virtual machines for a very long time here. These days, I can't give that Pentium away because a used system for $75 is much faster and more capable.

I ran multiple Core2 Duo computers with VT-x and has 20 VMs running one at least one of them for years. I was using Xen initially, then moved to KVM/QEMU. Worked great for the time, though faster CPUs with lower power needs is always better. I had an E6600 C2D eating 125W for years here. Added an E8400, then an X8600 ... all C2D systems, before I started moving in Core i5/i7 boxes. They made a bunch of heat, so I started getting newer CPUs which used 50% less power. The savings in my power bill usually paid for the cooler, faster, newer, CPUs in about 2 yrs. I have 1 CPU left using 125W - all the others are 65W or less and over 5x faster.

Just something to consider.

Since "Windows 10 Home", I am assuming it's at least 64bit... How much memory and what CPU?

Because there is another way also... You could do Ubuntu Server, Primary, running 24x7, with KVM, with on-demand minimal Desktop...With your Windows 10 Home migrated to KVM VM Guest.. That way your Server Services are not interrupted by your intermittent use of that.

Just another option..

But what you describe, is not what you said. If the PC is down, powered off, and woke up by WOL... That is not 24x7x365 service. Just saying. (Are you trying to save money on your electrical bill from that?)

[MAFoElffen]

If you 'Try' an lightweight Ubuntu Flavor... and have your Windows as a VM Guest of that host, it's still there. You could always keep a backup to revert back.

Who knows. You might find that you use that VM less and less as you familiarize yourself with Linux Desktops... and later find that you might not use that VM enough to keep it going. Microsoft is abandoning users of older hardware for any release upgrade path to Windows 11. This will be a personal consideration to you eventually.

2008-2009
I mean year purchased and probably manufactured

Because this PC is very old, and Windows 10 Home 64-bit, I think Hyper-V Not supported, but ONLY VirtualBox is supported as of running VMs…

This is intel core 2 quad 64-bit, DDR2 8GB RAM, HDD Windows 10 Home 64-bit

BIOS And Not UEFI
MBR and Not GPT

Default boot OS can be configured...? If yes, this depends on OS installed lastly...?

I'd just install the advance version of 22.04. Server distros are quite stable.

You can use gpt with old BIOS. Its just you need a bios_grub partition of 1 or 2MB unformatted with bios_grub flag.
I started converting to gpt back in 2010 with old BIOS system. Now all drives are gpt and only one retired laptop is BIOS, but also gpt.

GPT Advantages (older 2010 but still valid) see post#2 by srs5694:

If you convert from MBR to gpt it will totally erase drive, so have good backups.
And if you want to keep Windows, you have to stay with MBR as Windows only boots from gpt with UEFI.
