[Warlock1111]

i want to install Mint on my laptop but i have only one drive.
i never dual botted on the same drive before. so can anyone n give me some tips and/or have a taturial he can recomend?

few things i should point out:
1.i set up a seperate partition for Mint
2:all of my data is saved on external drive so there is no risk for data loss

1. Install Windows 10.
2. Use its Disk Manager and split the disk into two parts as you want. The LM needs at least 100 GB to have storage space as well. It's a good idea to allocate about 50GB for Timeshift so you can restore your system if needed. It is enough to keep 2-3 backups.
3. IMPORTANT: Download Windows Update Blocker /WUB/, unzip it in Windows and run it. Block updates. This will save you problems because Windows on update will overwrite the boot partition and prevent you from running LM.
4. Run LM from a flash stick and select "something else" when installing.
5. Set the first free partition to / - ext4. The LM will be installed there.
6. Set the other partition /50GB/ to format - ext4. After installation, select it for Timeshift.
6. After the LM installation, it will boot. Open a terminal and run the command: sudo update-grub
7. Restart the system.
After the reboot you will see a menu to select the OS.
Good luck!

Note: You lose nothing from blocked Windows updates. I used Windows from 3.11 until today, never updated and never had any problems from that.

You are assuming OP is installing on EFI mode ( to be confirmed). In case Windows is installed on BIOS mode (i.e. if installing LM 21.X on BIOS mode):

a)Be sure partition number when creating new ones. On MBR disks there must be four primary partitions max or three primary partitions and an extended one.

Sometimes you need to remove previous Windows partitions and/or create that extended partition on point 2 and/or partitions you create on point 4-5 must be logical not primary.

In case of doubts take a Windows Disk Manager's screenshot or post back inxi -SM; sudo parted -l results when booting Linux Mint Live.

b)You will receive a warning about an EFI partition is needed because a Mint's installer bug (between first 6 and second 6 point ). Ignore it and Continue

1.wait what?! can you eliborate on the partition thing?

2.

You are assuming OP is installing on EFI mode

the OP you are reffering is windows? or Linux?
assuming its windows what should i do if it installed on EFI mode?

Notice my post was only to confirm boot mode (it was unknown) and just in case of Windows installed on Legacy BIOS mode. If Windows is installed on UEFI mode

1.It must be GPT partitioning scheme, so no problem with primary partitions.

2.Just install Mint following diabolicbg indications.
