Problem with partition installing Ubuntu 24.04 dual boot

[silvio777]

Sorry but could this istruction ruin my windows 7 or i will be always able to reboot almost windows 7? What does it do? Thanks

Because you (sort of) have to use the Legacy method - in a computer that apparently is UEFI based therefore Windows 7 with the last SP could have been installed in UEFI mode (a moot point anyway because you shouldn’t be using any Windows 7, 9 or even 10) - now you have to also install Ubuntu in the same mode. That implies the bootloader in the MBR will be replaced by Ubuntu’s GRUB. Although this should enable booting from other OSes (Windows in this case), it’s much more rigid than what you’d get with UEFI mode where all bootloaders coexist in the ESP, a special partition. The practical implication being you can’t boot Windows independently.

@silvio777

could this istruction ruin my windows 7

[ -d /sys/firmware/efi ] && echo "UEFI" || echo "Legacy"

This command will not ruin Windows.
It only reports the mode after you have booted your USB installer.
The answer will be either UEFI or Legacy.
You are looking for Legacy.

Hi,
I can’t double-click to expand SDA1. Nothing happens

I ran
sudo fdisk -l | sed -e ‘/Disk /dev/loop/,+5d’
to get the partitions without the extraneous loop devices:

To verify my boot, I ran:
[ -d /sys/firmware/efi ] && echo “UEFI” || echo “Legacy”
resulting in: UEFI

As my Windows 7 is installed in Legacy Mode, I’ve tried to understand how to set this mode in BIOS but I have some problems

Actually, these are the two scenarios I see for setting the BIOS:

1. If in BIOS I disable UEFI Boot

then in the selection I only see my USB stick but if I select it then Windows 7 immediately starts anyway

2. If in BIOS I enable UEFI Boot

then in the selection I see these two options but if I select pen drive Kingstone then Windows 7 starts anyway, whereas if I select UEFI: USB USB Hard Drive , it uses my pen drive but in UEFI mode

Your USB attached
UEFI Boot disabled
Select Hard Drive BBS priorities

What do you see?

[yancek]

If you are in the BIOS and you select the Kingston are you not able to use the up arrow to move it above the Hitachi (windows 7) entry? Usually need to F10, Save and Exit to make the change. Don’t you have an option to make a one time change of the boot device on that machine?

[silvio777]

If I disable UEFI boot and then go to “Hard Drive BBS Priorities” and set my Kingstone DataTravel 3.00000 pen drive as the first choice, save, and boot, I see the message:

GRUB Loading

Welcome…

for a second, then it goes back to a black screen with ASUS written on it, then GRUB Loading again, and it loops endlessly until I go back to boot settings.

@silvio777

GRUB Loading

Promising start

@silvio777

then GRUB Loading again, and it loops endlessly

Disappointing outcome

There could be a number of reasons for this:-

• Use a different USB port
• Do not connect to the internet
• Check the integrity of the ISO
• The USB/Thumb/Flash device is faulty
• Use different software to create the USB

• Lighter flavour req’d - Try Xubuntu 24.04 or Lubuntu 24.04

@silvio777

My PC is an old ASUS

Can you confirm that your PC is 64-bit?

[silvio777]

The USB stick is new and thus the integrity of the ISO shouldn’t be a problem ‘cause if I boot in UEFI, I can use Ubuntu Live.
I’ll try not using Rufus, but something else and I won’t connect to the internet.
I’ve read online that disabling Fast/Quick Boot in the BIOS could solve the problem, but I can’t find this option in my BIOS.
I confirm my pc is 64 bit
