+# 🚀 Arch Linux Dual Boot Guide (Speedrun Version)
+
+## **1. Prepare Windows**
+- **Shrink Windows Partition**  
+  - Open `diskmgmt.msc`, shrink `C:` by **50GB+** (Unallocated Space).  
+- **Check Boot Mode**  
+  - Press `Win + R`, type `msinfo32`, check **BIOS Mode**:  
+    - **UEFI** → Continue with UEFI  
+    - **Legacy (MBR)** → Use MBR installation  
+
+---
+
+## **2. Boot into Arch Live USB**
+- Create USB:  
+  ```sh
+  dd if=archlinux.iso of=/dev/sdX bs=4M status=progress
+  ```
+- Boot from USB in BIOS.
+
+---
+
+## **3. Partition the Disk**
+```sh
+lsblk  # Identify your disk (e.g., /dev/nvme0n1)
+cfdisk /dev/nvme0n1
+```
+- **Keep Windows partitions**  
+- Create **Linux Root Partition** (`ext4`, **50GB+**)
+- **(Optional)** Create Swap Partition (8GB)  
+
+---
+
+## **4. Format & Mount**
+```sh
+mkfs.ext4 /dev/nvme0n1p3
+mount /dev/nvme0n1p3 /mnt
+mkdir -p /mnt/boot/efi
+mount /dev/nvme0n1p1 /mnt/boot/efi  # Use Windows' EFI partition
+```
+*(If Swap)*
+```sh
+mkswap /dev/nvme0n1p4
+swapon /dev/nvme0n1p4
+```
+
+---
+
+## **5. Install Arch**
+```sh
+pacstrap /mnt base linux linux-firmware vim
+genfstab -U /mnt >> /mnt/etc/fstab
+arch-chroot /mnt
+```
+
+---
+
+## **6. Basic Config**
+```sh
+ln -sf /usr/share/zoneinfo/Region/City /etc/localtime
+hwclock --systohc
+echo "LANG=en_US.UTF-8" > /etc/locale.conf
+echo "archlinux" > /etc/hostname
+passwd  # Set root password
+```
+
+---
+
+## **7. Install & Configure GRUB**
+```sh
+pacman -S grub efibootmgr os-prober
+grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
+os-prober
+grub-mkconfig -o /boot/grub/grub.cfg
+```
+
+---
+
+## **8. Finish Installation**
+```sh
+exit
+umount -R /mnt
+reboot
+```
+- **Select Arch Linux from GRUB** 🎉  
+- If Windows is missing from GRUB:
+  ```sh
+  os-prober
+  grub-mkconfig -o /boot/grub/grub.cfg
+  ```
+
+---
+
+## **Done!** 🚀
